Descent from Genghis Khan

From Wikipedia, the free encyclopedia

Descent from Genghis Khan in East Asia is well-documented by Chinese sources. His descent in West Asia and Europe was documented through the 14th century, in texts written by Rashid-al-Din Hamadani and other Muslim historians. With the advent of genealogical DNA testing, a larger and broader circle of people have begun to claim descent from Genghis Khan.

Paternity of Jochi

Jochi, Genghis Khan's eldest son, had many more recorded progeny than his brothers Ögedei, Chagatai, and Tolui—but there is some doubt over his paternity. According to The Secret History of the Mongols, the boy was sent to Genghis by Chilger, who had kidnapped his first wife Börte, keeping her in captivity for about a year. In one passage, Chagatai refers to Jochi as "bastard" (although the true meaning of the Mongol term is obscure). To this, Genghis Khan responds: "How dare you talk about Jochi like this? Is not he the eldest of my heirs? That I never heard such wicked words again!" (p255). All in all, Genghis Khan pronounces the words "Jochi is my eldest son" thrice (p210, 242, 254).

Modern historians speculate that Jochi's disputed paternity was the reason for his eventual estrangement from his father and for the fact that his descendants never succeeded to the imperial throne. On the other hand, Genghis always treated Jochi as his first son, while the failure of the Jochid succession may be explained by Jochi's premature death (which may have excluded his progeny from succession).

Another important consideration is that Genghis' descendants intermarried frequently. For instance, the Jochids took wives from the Ilkhan dynasty of Persia, whose progenitor was Hulagu Khan. As a consequence, it is likely that many Jochids had other sons of Genghis Khan among their maternal ancestors.

Asia

Asian dynasties descended from Genghis Khan included the Yuan dynasty (Kublaids) of China, the Hulaguids of Persia, the Jochids of the Golden Horde, the Shaybanids of Siberia, and the Astrakhanids of Central Asia. As a rule, the Genghisid descent played a crucial role in Tatar politics. For instance, Mamai (1335–1380) had to exercise his authority through a succession of puppet khans but could not assume the title of khan himself because he lacked Genghisid lineage.

Timur Lenk (1336–1405), the founder of the Timurid dynasty, claimed descent from Genghis Khan. He associated himself with the family of Chagatai Khan through marriage. He never assumed the title Khan for himself, but employed two members of the Chagatai clan as formal heads of state. The Mughal imperial family of the Indian subcontinent descended from Timur through Babur and also from Genghis Khan (through his son Chagatai Khan).

The ruling Wang Clan of the Korean Goryeo dynasty became descendants of the Genghisids through the marriage between King Chungnyeol (reigned 1274–1308) and a daughter of Kublai Khan. All subsequent rulers of Korea for the next 80 years, through King Gongmin, also married Borjigid princesses.

At a later period, Tatar potentates of Genghisid stock included the khans of Qazan and Qasim (notably a Russian tsar, Simeon Bekbulatovich, formally Grand Prince of All Rus' from 1575 to 1576, died 1616) and the Giray dynasty, which ruled the Khanate of Crimea until 1783.

Other countries ruled by dynasties with (potential) descent from Genghis Khan are Moghulistan (through Chagatai Khan), the Northern Yuan dynasty (Kublaids), Kara Del (through Chagatai Khan), Khanate of Kazan (through Jochi), Qasim Khanate (through Ulugh Muhammad), the Kazakh Khanate (through Urus Khan), the Great Horde (remnant of the Golden Horde), the Khanate of Bukhara (Shaybanid dynasty, later Janid dynasty, descendants of Astrakhanids), the Khanate of Khiva (descendants of Shiban, the fifth son of Jochi), the Yarkent Khanate (through Chagatai Khan), the Arghun dynasty (claimed their descent Ilkhanid-Mongol Arghun Khan), the Kumul Khanate (through Chagatai Khan) and the Khanate of Kokand (Shaybanid dynasty).

The khans of the Khoshut Khanate were indirect descendants. They were descendants from a younger brother of Genghis Khan, Qasar.

As the Russian Empire absorbed Turkic polities, their Genghizid rulers frequently entered the Russian service. For instance, Kuchum's descendants became Russified as the Tsarevichs of Siberia. Descendants of Ablai Khan assumed in Russia the name of Princes Valikhanov. All these families asserted their Genghisid lineage. The only extant family of this group is the House of Giray, whose members left Soviet Russia for the United States and United Kingdom.

The Qing dynasty of China completely exterminated one branch (Ligdan Khan's descendants) of the Borjigids after an anti-Qing revolt in 1675 by Ejei Khan's brother Abunai and Abunai's son Borni against the Qing. The Qing Emperors then placed the Chahar Mongols under their direct rule. The Emperors of the Qing dynasty and the Emperor of Manchukuo were also indirect descendants by Qasar, a younger brother of Genghis Khan.

The Crimean Khanate Khan Meñli I Giray was the maternal grandfather of Suleiman the Magnificent through his daughter, Ayşe Hafsa Sultan. Thereafter, the Ottoman dynasty also claimed descent from Genghis Khan through his son Jochi.

Russia and eastern Europe

After the Mongol invasion of Rus', members of the Rurikid dynasty of Russia often sought marriages with Mongol princesses. Many of these marriages were sought for military and political advantage, as the Russian princes were often feuding with each other. A marriage alliance with the Mongol horde gave them better leverage in their struggles against each other.

After spending several years at the Mongol court, Yury of Moscow sought to marry Konchak, a sister of Öz Beg Khan, which the Khan gave consent to. Konchak converted to Christianity, and was given the baptismal name Agatha. This marriage was a strategic political alliance that transformed Moscow in to the newest regional power in Russia, and severely weakened the power away from the Russian Prince of Tver, formerly a major power prior to the Mongol invasions.

Berke's nephew adopted the Christian name Peter and founded St. Peter's Monastery in Rostov, where his descendants existed for centuries as boyars.

Gleb, the Russian Prince of Beloozero, married the only daughter of Sartaq Khan. She was given the baptismal name Theodora in the year 1257. From this marriage descends the House of Belozersk, whose scions include Dmitry Ukhtomsky and Belosselsky-Belozersky family.

Ties between Russian and Mongol royal families persisted for a long time. St. Fyodor the Black married a daughter of Mengu-Timur. She was baptized and given the Christian name Anna. Male-line descendendants of Fyodor's marriage to the Tatar Princess include all rulers of Yaroslavl (from then on) and over 20 princely families (such as the Shakhovskoy, Lvov, or Prozorovsky, among others). After the 1917 revolution, some of these families were expelled from Russia.

According to Marie Favereau, a feeling of mutual respect between the Russian and Mongol sides had developed. The fact that Russian princes could marry Mongol princesses is a sign that Mongol lords trusted their northern vassals. She also notes that, even after the adoption of Islam by the Mongol khans, the Mongols never took Russian women as concubines, unlike the Ottoman sultans.

DNA evidence

Scientists have speculated about the Y-chromosomal haplogroup (and therefore patrilineal ancestry) of Genghis Khan.

Zerjal et al. (2003) identified a Y-chromosomal lineage haplogroup C*(xC3c) present in about 8% of men in a region of Asia "stretching from northeast China to Uzbekistan", which would be around 16 million men at the time of publication, "if [Zerjal et al's] sample is representative." The authors propose that the lineage was likely carried by male-line descendants of Genghis Khan, because of its presence in certain ethnic groups rumored to be their descendants. One study published in the Russian Journal of Genetics found that 24% of Mongolians carry this haplogroup, and that it occurs in low frequencies in neighboring Turkic states (with the exception of Kazakhstan).

A white paper by the American Society of Human Genetics Ancestry and Ancestry Testing Task Force, Royal et al. (2010) observed the Zerjal et al. hypothesis:

Although such a connection is by no means impossible, we currently have no way of assessing how much confidence to place in such a connection. We emphasize, however, that whenever formal inferences about population history have been attempted with uniparental systems, the statistical power is generally low. Claims of connections, therefore, between specific uniparental lineages and historical figures or historical migrations of peoples are merely speculative.

In a 2017 review paper published in Human Genetics, authors Chiara Batini and Mark Jobling cast doubts on Zerjal's 2003 theory that Genghis Khan is linked to haplogroup C:

Ancient DNA data (Lkhagvasuren et al. 2016) from remains in high-status Mongolian graves dated to 1130–1250 CE revealed MSY lineages belonging to hg R1b, rather than hg C: there are a number of explanations for such findings, but taken at face value, they do not support the Genghis Khan hypothesis for the origin of the widespread Asian expansion lineage (Zerjal et al. 2003).

Proposed candidate haplogroups and haplotypes

Over the years, following haplogroups have been proposed as candidades 

  • Haplogroup C-M217
    • C2b1a3a1c2-F5481 (C-M217*-Star Cluster / clade of C2*-ST): Widespread in Central Asia among Kazakhs, Hazaras and ordinary commoner Mongols. The Kerey clan of the Kazakhs have a high amount of the C3* star-cluster (C2*-ST) Y chromosome and is very high among Hazaras, Kazakhs and Mongols in general.
      However, in 2017 a Chinese research team suggested that the Y chromosome C-M217*-Star Cluster likely traces back to ordinary Mongol warriors, rather than Genghis Khan, and that "a direct linking of haplogroup C-M217 to Genghis Khan has yet to be discovered."
      In a review paper published in Human Genetics, authors Chiara Batini and Mark Jobling cast doubts on Zerjal's 2003 theory that Genghis Khan is linked to haplogroup C
    • C2c1a1a1-M407: Carried by Mongol descendants of the Northern Yuan ruler from 1474 to 1517, Dayan Khan, an alleged male line descendant of Genghis Khan.
    • C2b1a1b1-F1756 : In 2019, a Chinese research team study suggested that Haplogroup C2b1a1b1-F1756 might be a candidate of the true Y lineage of Genghis Khan.
      The Lu clan claimed to be the descendants of Khulgen, the sixth son of Genghis Khan. A genetic study of the molecular genealogy of Northwest China shows that some members of Lu belong to Y-DNA haplogroup C2b1a1b1 F1756. This haplogroup is also observed in the Tore clan from Kazakhstan, who have claimed to be paternal descendants of Jochi, the first son of Genghis Khan. However, the claim that the Lu clan is descendant of Khulgen is controversial and is disputed by several other studies.
  • Haplogroup O-M175
  • Haplogroup R1b
    • Research published in 2016 suggested that Genghis possibly belonged to the haplogroup Haplogroup R1b (R1b-M343). Five bodies, dating from about 1130–1250, were found in graves in Tavan Tolgoi, Mongolia. The authors suggested they were members of the Golden Family, and linked the spread of R1b-M343 to the former territories of the Mongol Empire. The authors suggested that the Tavan Tolgoi bodies the female lineages of Genghis Khan's Borjigin clan, or to Genghis Khan's male lineage, rather than the Ongud clan.
  • Haplogroup Q-M242

Popular culture

  • In The Hitchhiker's Guide to the Galaxy, the motorway contractor Mr. Prosser is (unknown to himself) a direct patrilineal descendant of Genghis Khan. This manifests itself in a predilection for fur hats, a desire to have axes hanging above his front door, being slightly overweight and occasional visions of screaming Mongol hordes.
  • Fictional character Shiwan Khan, who is described as the last living descendant of Genghis appears in The Shadow, a collection of serialized dramas, originally on 1930s radio. He also appeared in the 1994 film adaptation, The Shadow.
  • Marvel Comics supervillains the Mandarin and his son Temugin, both primarily opponents of Iron Man, are descendants of Genghis Khan.
  • In a spoof of the 1989 comedy film Bill & Ted's Excellent Adventure by the sketch show Robot Chicken, a crowd member admonishes Bill and Ted for choosing Genghis Khan to bring to the future as he slaughtered millions, erroneously claiming 6% of all Mongolians were his direct descendants resulting from rape.

Genealogy

From Wikipedia, the free encyclopedia

Genealogy (from Ancient Greek γενεαλογία (genealogía) 'the making of a pedigree') is the study of families, family history, and the tracing of their lineages. Genealogists use oral interviews, historical records, genetic analysis, and other records to obtain information about a family and to demonstrate kinship and pedigrees of its members. The results are often displayed in charts or written as narratives. The field of family history is broader than genealogy, and covers not just lineage but also family and community history and biography.

The record of genealogical work may be presented as a "genealogy", a "family history", or a "family tree". In the narrow sense, a "genealogy" or a "family tree" traces the descendants of one person, whereas a "family history" traces the ancestors of one person, but the terms are often used interchangeably. A family history may include additional biographical information, family traditions, and the like.

The pursuit of family history and origins tends to be shaped by several motives, including the desire to carve out a place for one's family in the larger historical picture, a sense of responsibility to preserve the past for future generations, and self-satisfaction in accurate storytelling. Genealogy research is also performed for scholarly or forensic purposes, or to trace legal next of kin to inherit under intestacy laws.

Overview

Amateur genealogists typically pursue their own ancestry and that of their spouses. Professional genealogists may also conduct research for others, publish books on genealogical methods, teach, or produce their own databases. They may work for companies that provide software or produce materials of use to other professionals and to amateurs. Both try to understand not just where and when people lived but also their lifestyles, biographies, and motivations. This often requires—or leads to—knowledge of antiquated laws, old political boundaries, migration trends, and historical socioeconomic or religious conditions.

Genealogists sometimes specialize in a particular group, e.g., a Scottish clan; a particular surname, such as in a one-name study; a small community, e.g., a single village or parish, such as in a one-place study; or a particular, often famous, person. Bloodlines of Salem is an example of a specialized family-history group. It welcomes members who can prove descent from a participant of the Salem Witch Trials or who simply choose to support the group.

Genealogists and family historians often join family history societies, where novices can learn from more experienced researchers. Such societies generally serve a specific geographical area. Their members may also index records to make them more accessible or engage in advocacy and other efforts to preserve public records and cemeteries. Some schools engage students in such projects as a means to reinforce lessons regarding immigration and history. Other benefits include family medical histories for families with serious medical conditions that are hereditary.

The terms "genealogy" and "family history" are often used synonymously, but some entities offer a slight difference in definition. The Society of Genealogists, while also using the terms interchangeably, describes genealogy as the "establishment of a pedigree by extracting evidence, from valid sources, of how one generation is connected to the next" and family history as "a biographical study of a genealogically proven family and of the community and country in which they lived".

Motivation

Individuals conduct genealogical research for a number of reasons.

Personal or medical interest

Private individuals research genealogy out of curiosity about their heritage. This curiosity can be particularly strong among those whose family histories were lost or unknown due to, for example, adoption or separation from family through divorce, death, or other situations. In addition to simply wanting to know more about who they are and where they came from, individuals may research their genealogy to learn about any hereditary diseases in their family history.

There is a growing interest in family history in the media as a result of advertising and television shows sponsored by large genealogy companies, such as Ancestry.com. This, coupled with easier access to online records and the affordability of DNA tests, has both inspired curiosity and allowed those who are curious to easily start investigating their ancestry.

Community or religious obligation

In communitarian societies, one's identity is defined as much by one's kin network as by individual achievement, and the question "Who are you?" would be answered by a description of father, mother, and tribe. New Zealand Māori, for example, learn whakapapa (genealogies) to discover who they are.

Family history plays a part in the practice of some religious belief systems. For example, The Church of Jesus Christ of Latter-day Saints (LDS Church) has a doctrine of baptism for the dead, which necessitates that members of that faith engage in family history research.

In East Asian countries that were historically shaped by Confucianism, many people follow a practice of ancestor worship as well as genealogical record-keeping. Ancestors' names are inscribed on tablets and placed in shrines, where rituals are performed. Genealogies are also recorded in genealogy books. This practice is rooted in the belief that respect for one's family is a foundation for a healthy society.

Establishing identity

Royal families, both historically and in modern times, keep records of their genealogies in order to establish their right to rule and determine who will be the next sovereign. For centuries in various cultures, one's genealogy has been a source of political and social status.

Some countries and indigenous tribes allow individuals to obtain citizenship based on their genealogy. In Ireland and in Greece, for example, an individual can become a citizen if one of their grandparents was born in that country, regardless of their own or their parents' birthplace. In societies such as Australia or the United States, by the 20th century, there was growing pride in the pioneers and nation-builders. Establishing descent from these was, and is, important to lineage societies, such as the Daughters of the American Revolution and The General Society of Mayflower Descendants. Modern family history explores new sources of status, such as celebrating the resilience of families that survived generations of poverty or slavery, or the success of families in integrating across racial or national boundaries. Some family histories even emphasize links to celebrity criminals, such as the bushranger Ned Kelly in Australia.

Legal and forensic research

Lawyers involved in probate cases do genealogy to locate heirs of property.

Detectives may perform genealogical research using DNA evidence to identify victims of homicides or perpetrators of crimes.

Scholarly research

Historians and geneticists may carry out genealogical research to gain a greater understanding of specific topics in their respective fields, and some may employ professional genealogists in connection with specific aspects of their research. They also publish their research in peer-reviewed journals.

The introduction of postgraduate courses in genealogy in recent years has given genealogy more of an academic focus, with the emergence of peer-reviewed journals in this area. Scholarly genealogy is beginning to emerge as a discipline in its own right, with an increasing number of individuals who have obtained genealogical qualifications carrying out research on a diverse range of topics related to genealogy, both within academic institutions and independently.

Discrimination and persecution

In the US, the "one-drop rule" asserted that any person with even one ancestor of black ancestry ("one drop" of "black blood") was considered black. It was codified into the law of some States (e.g. the Racial Integrity Act of 1924) to reinforce racial segregation.

Genealogy was also used in Nazi Germany to determine whether a person was considered a "Jew" or a "Mischling" (Mischling Test), and whether a person was considered as "Aryan" (Ahnenpass).

History

Historically, in Western societies, the focus of genealogy was on the kinship and descent of rulers and nobles, often arguing or demonstrating the legitimacy of claims to wealth and power. The term often overlapped with heraldry, in which the ancestry of royalty was reflected in their coats of arms. Modern scholars consider many claimed noble ancestries to be fabrications, such as the Anglo-Saxon Chronicle that traced the ancestry of several English kings to the god Woden. Some family trees have been maintained for considerable periods. The family tree of Confucius has been maintained for over 2,500 years and is listed in the Guinness Book of World Records as the largest extant family tree. The fifth edition of the Confucius Genealogy was printed in 2009 by the Confucius Genealogy Compilation Committee (CGCC).

Modern times

In modern times, genealogy has become more widespread, with commoners as well as nobility researching and maintaining their family trees. Genealogy received a boost in the late 1970s with the television broadcast of Roots: The Saga of an American Family by Alex Haley. His account of his family's descent from the African tribesman Kunta Kinte inspired many others to study their own lines.

With the advent of the Internet, the number of resources readily accessible to genealogists has vastly increased, resulting in an explosion of interest in the topic. Genealogy is one of the most popular topics on the Internet. The Internet has become a major source not only of data for genealogists but also of education and communication.

India

Some notable places where traditional genealogy records are kept include Hindu genealogy registers at Haridwar (Uttarakhand), Varanasi and Allahabad (Uttar Pradesh), Kurukshetra (Haryana), Trimbakeshwar (Maharashtra), and Chintpurni (Himachal Pradesh).

United States

Genealogical research in the United States was first systematized in the early 19th century, especially by John Farmer (1789–1838). Before Farmer's efforts, tracing one's genealogy was seen as an attempt by the American colonists to secure a measure of social standing, an aim that was counter to the new republic's egalitarian, future-oriented ideals (as outlined in the Constitution). As Fourth of July celebrations commemorating the Founding Fathers and the heroes of the Revolutionary War became increasingly popular, however, the pursuit of "antiquarianism", which focused on local history, became acceptable as a way to honor the achievements of early Americans. Farmer capitalized on the acceptability of antiquarianism to frame genealogy within the early republic's ideological framework of pride in one's American ancestors. He corresponded with other antiquarians in New England, where antiquarianism and genealogy were well established, and became a coordinator, booster, and contributor to the growing movement. In the 1820s, he and fellow antiquarians began to produce genealogical and antiquarian tracts in earnest, slowly gaining a devoted audience among the American people. Though Farmer died in 1839, his efforts led to the creation of the New England Historic Genealogical Society (NEHGS), one of New England's oldest and most prominent organizations dedicated to the preservation of public records. NEHGS publishes the New England Historical and Genealogical Register.

The Genealogical Society of Utah, founded in 1894, later became the Family History Department of the Church of Jesus Christ of Latter-day Saints. The department's research facility, the Family History Library, which Utah.com states is "the largest genealogical library in the world", was established to assist in tracing family lineages for special religious ceremonies which Latter-day Saints believe will seal family units together for eternity. Latter-day Saints believe that this fulfilled a biblical prophecy stating that the prophet Elijah would return to "turn the heart of the fathers to the children, and the heart of the children to their fathers." There is a network of church-operated Family History Centers all over the country and around the world, where volunteers assist the public with tracing their ancestors. Brigham Young University offers bachelor's degree, minor, and concentration programs in Family History and is the only school in North America to offer this.

The American Society of Genealogists is the scholarly honorary society of the U.S. genealogical field. Founded by John Insley Coddington, Arthur Adams, and Meredith B. Colket, Jr., in December 1940, its membership is limited to 50 living fellows. ASG has semi-annually published The Genealogist, a scholarly journal of genealogical research, since 1980. Fellows of the American Society of Genealogists, who bear the post-nominal acronym FASG, have written some of the most notable genealogical materials of the last half-century.

Some of the most notable scholarly American genealogical journals are The American Genealogist, National Genealogical Society Quarterly, The New England Historical and Genealogical Register, The New York Genealogical and Biographical Record, and The Genealogist.

Research process

Genealogical research is a complex process that uses historical records and sometimes genetic analysis to demonstrate kinship. Reliable conclusions are based on the quality of sources (ideally, original records), the information within those sources, (ideally, primary or firsthand information), and the evidence that can be drawn (directly or indirectly), from that information. In many instances, genealogists must skillfully assemble indirect or circumstantial evidence to build a case for identity and kinship. All evidence and conclusions, together with the documentation that supports them, is then assembled to create a cohesive genealogy or family history.

Genealogists begin their research by collecting family documents and stories. This creates a foundation for documentary research, which involves examining and evaluating historical records for evidence about ancestors and other relatives, their kinship ties, and the events that occurred in their lives. As a rule, genealogists begin with the present and work backwards in time. Historical, social, and family context is essential to achieving correct identification of individuals and relationships. Source citation is also important when conducting genealogical research. To keep track of collected material, family group sheets and pedigree charts are used. Formerly handwritten, these can now be generated by genealogical software.

Genetic analysis

Because a person's DNA contains information that has been passed down relatively unchanged from early ancestors, analysis of DNA is sometimes used for genealogical research. Three DNA types are of particular interest. Mitochondrial DNA (mtDNA) is contained in the mitochondria of the egg cell and is passed down from a mother to all of her children, both male and female; however, only females pass it on to their children. Y-DNA is present only in males and is passed down from a father to his sons (direct male line) with only minor mutations occurring over time. Autosomal DNA (atDNA), is found in the 22 non-sex chromosomes (autosomes) and is inherited from both parents; thus, it can uncover relatives from any branch of the family. A genealogical DNA test allows two individuals to find the probability that they are, or are not, related within an estimated number of generations. Individual genetic test results are collected in databases to match people descended from a relatively recent common ancestor. See, for example, the Molecular Genealogy Research Project. Some tests are limited to either the patrilineal or the matrilineal line.

Collaboration

Most genealogy software programs can export information about persons and their relationships in a standardized format called a GEDCOM. In that format, it can be shared with other genealogists, added to databases, or converted into family web sites. Social networking service (SNS) websites allow genealogists to share data and build their family trees online. Members can upload their family trees and contact other family historians to fill in gaps in their research. In addition to the (SNS) websites, there are other resources that encourage genealogists to connect and share information, such as rootsweb.ancestry.com and rsl.rootsweb.ancestry.com.

Volunteerism

Volunteer efforts figure prominently in genealogy. These range from the extremely informal to the highly organized.

On the informal side are the many popular and useful message boards such as Rootschat and mailing lists on particular surnames, regions, and other topics. These forums can be used to try to find relatives, request record lookups, obtain research advice, and much more. Many genealogists participate in loosely organized projects, both online and off. These collaborations take numerous forms. Some projects prepare name indexes for records, such as probate cases, and publish the indexes, either online or off. These indexes can be used as finding aids to locate original records. Other projects transcribe or abstract records. Offering record lookups for particular geographic areas is another common service. Volunteers do record lookups or take photos in their home areas for researchers who are unable to travel.

Those looking for a structured volunteer environment can join one of thousands of genealogical societies worldwide. Most societies have a unique area of focus, such as a particular surname, ethnicity, geographic area, or descendancy from participants in a given historical event. Genealogical societies are almost exclusively staffed by volunteers and may offer a broad range of services, including maintaining libraries for members' use, publishing newsletters, providing research assistance to the public, offering classes or seminars, and organizing record preservation or transcription projects.

Software

Gramps is an example of genealogy software.

Genealogy software is used to collect, store, sort, and display genealogical data. At a minimum, genealogy software accommodates basic information about individuals, including births, marriages, and deaths. Many programs allow for additional biographical information, including occupation, residence, and notes, and most also offer a method for keeping track of the sources for each piece of evidence. Most programs can generate basic kinship charts and reports, allow for the import of digital photographs and the export of data in the GEDCOM format (short for GEnealogical Data COMmunication) so that data can be shared with those using other genealogy software. More advanced features include the ability to restrict the information that is shared, usually by removing information about living people out of privacy concerns; the import of sound files; the generation of family history books, web pages and other publications; the ability to handle same-sex marriages and children born out of wedlock; searching the Internet for data; and the provision of research guidance. Programs may be geared toward a specific religion, with fields relevant to that religion, or to specific nationalities or ethnic groups, with source types relevant for those groups. Online resources involve complex programming and large data bases, such as censuses.

Records and documentation

Genealogists use a wide variety of records in their research. To effectively conduct genealogical research, it is important to understand how the records were created, what information is included in them, and how and where to access them.

List of record types

Records that are used in genealogy research include:

To keep track of their citizens, governments began keeping records of persons who were neither royalty nor nobility. In England and Germany, for example, such record keeping started with parish registers in the 16th century. As more of the population was recorded, there were sufficient records to follow a family. Major life events, such as births, marriages, and deaths, were often documented with a license, permit, or report. Genealogists locate these records in local, regional or national offices or archives and extract information about family relationships and recreate timelines of persons' lives.

In China, India and other Asian countries, genealogy books are used to record the names, occupations, and other information about family members, with some books dating back hundreds or even thousands of years. In the eastern Indian state of Bihar, there is a written tradition of genealogical records among Maithil Brahmins and Karna Kayasthas called "Panjis", dating to the 12th century CE. Even today these records are consulted prior to marriages.

In Ireland, genealogical records were recorded by professional families of senchaidh (historians) until as late as the mid-17th century. Perhaps the most outstanding example of this genre is Leabhar na nGenealach/The Great Book of Irish Genealogies, by Dubhaltach MacFhirbhisigh (d. 1671), published in 2004.

FamilySearch collections

The Family History Library, operated by the Church of Jesus Christ of Latter-day Saints, is the world's largest library dedicated to genealogical research.

The LDS Church has engaged in large-scale microfilming of records of genealogical value. Its Family History Library in Salt Lake City, Utah, houses over 2 million microfiche and microfilms of genealogically relevant material, which are also available for on-site research at over 4,500 Family History Centers worldwide.

FamilySearch's website includes many resources for genealogists: a FamilyTree database, historical records, digitized family history books, resources and indexing for African American genealogy such as slave and bank records, and a Family History Research Wiki containing research guidance articles.

Indexing ancestral information

Indexing is the process of transcribing parish records, city vital records, and other reports, to a digital database for searching. Volunteers and professionals participate in the indexing process. Since 2006, the microfilm in the FamilySearch granite mountain vault is in the process of being digitally scanned, available online, and eventually indexed.

For example, after the 72-year legal limit for releasing personal information for the United States Census was reached in 2012, genealogical groups cooperated to index the 132 million residents registered in the 1940 United States Census.

Between 2006 and 2012, the FamilySearch indexing effort produced more than 1 billion searchable records.

Record loss and preservation

Sometimes genealogical records are destroyed, whether accidentally or on purpose. In order to do thorough research, genealogists keep track of which records have been destroyed so they know when information they need may be missing. Of particular note for North American genealogy is the 1890 United States Census, which was destroyed in a fire in 1921. Although fragments survive, most of the 1890 census no longer exists. Those looking for genealogical information for families that lived in the United States in 1890 must rely on other information to fill that gap.

War is another cause of record destruction. During World War II, many European records were destroyed. Communists in China during the Cultural Revolution and in Korea during the Korean War destroyed genealogy books kept by families.

Often records are destroyed due to accident or neglect. Since genealogical records are often kept on paper and stacked in high-density storage, they are prone to fire, mold, insect damage, and eventual disintegration. Sometimes records of genealogical value are deliberately destroyed by governments or organizations because the records are considered to be unimportant or a privacy risk. Because of this, genealogists often organize efforts to preserve records that are at risk of destruction. FamilySearch has an ongoing program that assesses what useful genealogical records have the most risk of being destroyed, and sends volunteers to digitize such records. In 2017, the government of Sierra Leone asked FamilySearch for help preserving their rapidly deteriorating vital records. FamilySearch has begun digitizing the records and making them available online. The Federation of Genealogical Societies also organized an effort to preserve and digitize United States War of 1812 pension records. In 2010, they began raising funds, which were contribute by genealogists around the United States and matched by Ancestry.com. Their goal was achieved and the process of digitization was able to begin. The digitized records are available for free online.

Types of information

Genealogists who seek to reconstruct the lives of each ancestor consider all historical information to be "genealogical" information. Traditionally, the basic information needed to ensure correct identification of each person are place names, occupations, family names, first names, and dates. However, modern genealogists greatly expand this list, recognizing the need to place this information in its historical context in order to properly evaluate genealogical evidence and distinguish between same-name individuals. A great deal of information is available for British ancestry with growing resources for other ethnic groups.

Family names

Lineage of a family, c. 1809

Family names are simultaneously one of the most important pieces of genealogical information, and a source of significant confusion for researchers.

In many cultures, the name of a person refers to the family to which they belongs. This is called the family name, surname, or last name. Patronymics are names that identify an individual based on the father's name. For example, Marga Olafsdottir is Marga, daughter of Olaf, and Olaf Thorsson is Olaf, son of Thor. Many cultures used patronymics before surnames were adopted or came into use. The Dutch in New York, for example, used the patronymic system of names until 1687 when the advent of English rule mandated surname usage. In Iceland, patronymics are used by a majority of the population. In Denmark and Norway patronymics and farm names were generally in use through the 19th century and beyond, though surnames began to come into fashion toward the end of the 19th century in some parts of the country. Not until 1856 in Denmark and 1923 in Norway were there laws requiring surnames.

The transmission of names across generations, marriages and other relationships, and immigration may cause difficulty in genealogical research. For instance, women in many cultures have routinely used their spouse's surnames. When a woman remarried, she may have changed her name and the names of her children; only her name; or changed no names. Her birth name (maiden name) may be reflected in her children's middle names; her own middle name; or dropped entirely. Children may sometimes assume stepparent, foster parent, or adoptive parent names. Because official records may reflect many kinds of surname change, without explaining the underlying reason for the change, the correct identification of a person recorded identified with more than one name is challenging. Immigrants to America often Americanized their names.

Surname data may be found in trade directories, census returns, birth, death, and marriage records.

Given names

Genealogical data regarding given names (first names) is subject to many of the same problems as are family names and place names. Additionally, the use of nicknames is very common. For example, Beth, Lizzie or Betty are all common for Elizabeth, and Jack, John and Jonathan may be interchanged.

Middle names provide additional information. Middle names may be inherited, follow naming customs, or be treated as part of the family name. For instance, in some Latin cultures, both the mother's family name and the father's family name are used by the children.

Historically, naming traditions existed in some places and cultures. Even in areas that tended to use naming conventions, however, they were by no means universal. Families may have used them some of the time, among some of their children, or not at all. A pattern might also be broken to name a newborn after a recently deceased sibling, aunt or uncle.

An example of a naming tradition from England, Scotland and Ireland:

Child Namesake
1st son paternal grandfather
2nd son maternal grandfather
3rd son father
4th son father's oldest brother
1st daughter maternal grandmother
2nd daughter paternal grandmother
3rd daughter mother
4th daughter mother's oldest sister

Another example is in some areas of Germany, where siblings were given the same first name, often of a favourite saint or local nobility, but different second names by which they were known (Rufname). If a child died, the next child of the same gender that was born may have been given the same name. It is not uncommon that a list of a particular couple's children will show one or two names repeated.

Personal names have periods of popularity, so it is not uncommon to find many similarly named people in a generation, and even similarly named families; e.g., "William and Mary and their children David, Mary, and John".

Many names may be identified strongly with a particular gender; e.g., William for boys, and Mary for girls. Others may be ambiguous, e.g., Lee, or have only slightly variant spellings based on gender, e.g., Frances (usually female) and Francis (usually male).

Place names

While the locations of ancestors' residences and life events are core elements of the genealogist's quest, they can often be confusing. Place names may be subject to variant spellings by partially literate scribes. Locations may have identical or very similar names. For example, the village name Brockton occurs six times in the border area between the English counties of Shropshire and Staffordshire. Shifts in political borders must also be understood. Parish, county, and national borders have frequently been modified. Old records may contain references to farms and villages that have ceased to exist. When working with older records from Poland, where borders and place names have changed frequently in past centuries, a source with maps and sample records such as A Translation Guide to 19th-Century Polish-Language Civil-Registration Documents can be invaluable.

Available sources may include vital records (civil or church registration), censuses, and tax assessments. Oral tradition is also an important source, although it must be used with caution. When no source information is available for a location, circumstantial evidence may provide a probable answer based on a person's or a family's place of residence at the time of the event.

Maps and gazetteers are important sources for understanding the places researched. They show the relationship of an area to neighboring communities and may be of help in understanding migration patterns. Family tree mapping using online mapping tools such as Google Earth (particularly when used with Historical Map overlays such as those from the David Rumsey Historical Map Collection) assist in the process of understanding the significance of geographical locations.

Dates

It is wise to exercise extreme caution with dates. Dates are more difficult to recall years after an event, and are more easily mistranscribed than other types of genealogical data. Therefore, one should determine whether the date was recorded at the time of the event or at a later date. Dates of birth in vital records or civil registrations and in church records at baptism are generally accurate because they were usually recorded near the time of the event. Family Bibles are often a source for dates, but can be written from memory long after the event. When the same ink and handwriting is used for all entries, the dates were probably written at the same time and therefore will be less reliable since the earlier dates were probably recorded well after the event. The publication date of the Bible also provides a clue about when the dates were recorded since they could not have been recorded at any earlier date.

People sometimes reduce their age on marriage, and those under "full age" may increase their age in order to marry or to join the armed forces. Census returns are notoriously unreliable for ages or for assuming an approximate death date. Ages over 15 in the 1841 census in the UK are rounded down to the next lower multiple of five years.

Although baptismal dates are often used to approximate birth dates, some families waited years before baptizing children, and adult baptisms are the norm in some religions. Both birth and marriage dates may have been adjusted to cover for pre-wedding pregnancies.

Calendar changes must also be considered. In 1752, England and her American colonies changed from the Julian to the Gregorian calendar. In the same year, the date the new year began was changed. Prior to 1752 it was 25 March; this was changed to 1 January. Many other European countries had already made the calendar changes before England had, sometimes centuries earlier. By 1751 there was an 11-day discrepancy between the date in England and the date in other European countries.

For further detail on the changes involved in moving from the Julian to the Gregorian calendar, see: Gregorian calendar.

The French Republican Calendar or French Revolutionary Calendar was a calendar proposed during the French Revolution, and used by the French government for about 12 years from late 1793 to 1805, and for 18 days in 1871 in Paris. Dates in official records at this time use the revolutionary calendar and need "translating" into the Gregorian calendar for calculating ages etc. There are various websites which do this.

Occupations

Occupational information may be important to understanding an ancestor's life and for distinguishing two people with the same name. A person's occupation may have been related to his or her social status, political interest, and migration pattern. Since skilled trades are often passed from father to son, occupation may also be indirect evidence of a family relationship.

It is important to remember that a person may change occupations, and that titles change over time as well. Some workers no longer fit for their primary trade often took less prestigious jobs later in life, while others moved upwards in prestige. Many unskilled ancestors had a variety of jobs depending on the season and local trade requirements. Census returns may contain some embellishment; e.g., from labourer to mason, or from journeyman to master craftsman. Names for old or unfamiliar local occupations may cause confusion if poorly legible. For example, an ostler (a keeper of horses) and a hostler (an innkeeper) could easily be confused for one another. Likewise, descriptions of such occupations may also be problematic. The perplexing description "ironer of rabbit burrows" may turn out to describe an ironer (profession) in the Bristol district named Rabbit Burrows. Several trades have regionally preferred terms. For example, "shoemaker" and "cordwainer" have the same meaning. Finally, many apparently obscure jobs are part of a larger trade community, such as watchmaking, framework knitting or gunmaking.

Occupational data may be reported in occupational licences, tax assessments, membership records of professional organizations, trade directories, census returns, and vital records (civil registration). Occupational dictionaries are available to explain many obscure and archaic trades.

Reliability of sources

Information found in historical or genealogical sources can be unreliable and it is good practice to evaluate all sources with a critical eye. Factors influencing the reliability of genealogical information include: the knowledge of the informant (or writer); the bias and mental state of the informant (or writer); the passage of time and the potential for copying and compiling errors.

The quality of census data has been of special interest to historians, who have investigated reliability issues.

Knowledge of the informant

The informant is the individual who provided the recorded information. Genealogists must carefully consider who provided the information and what they knew. In many cases the informant is identified in the record itself. For example, a death certificate usually has two informants: a physician who provides information about the time and cause of death and a family member who provides the birth date, names of parents, etc.

When the informant is not identified, one can sometimes deduce information about the identity of the person by careful examination of the source. One should first consider who was alive (and nearby) when the record was created. When the informant is also the person recording the information, the handwriting can be compared to other handwriting samples.

When a source does not provide clues about the informant, genealogists should treat the source with caution. These sources can be useful if they can be compared with independent sources. For example, a census record by itself cannot be given much weight because the informant is unknown. However, when censuses for several years concur on a piece of information that would not likely be guessed by a neighbor, it is likely that the information in these censuses was provided by a family member or other informed person. On the other hand, information in a single census cannot be confirmed by information in an undocumented compiled genealogy since the genealogy may have used the census record as its source and might therefore be dependent on the same misinformed individual.

Motivation of the informant

Even individuals who had knowledge of the fact, sometimes intentionally or unintentionally provided false or misleading information. A person may have lied in order to obtain a government benefit (such as a military pension), avoid taxation, or cover up an embarrassing situation (such as the existence of a non-marital child). A person with a distressed state of mind may not be able to accurately recall information. Many genealogical records were recorded at the time of a loved one's death, and so genealogists should consider the effect that grief may have had on the informant of these records.

The effect of time

The passage of time often affects a person's ability to recall information. Therefore, as a general rule, data recorded soon after the event are usually more reliable than data recorded many years later. However, some types of data are more difficult to recall after many years than others. One type especially prone to recollection errors is dates. Also the ability to recall is affected by the significance that the event had to the individual. These values may have been affected by cultural or individual preferences.

Copying and compiling errors

Genealogists must consider the effects that copying and compiling errors may have had on the information in a source. For this reason, sources are generally categorized in two categories: original and derivative. An original source is one that is not based on another source. A derivative source is information taken from another source. This distinction is important because each time a source is copied, information about the record may be lost and errors may result from the copyist misreading, mistyping, or miswriting the information. Genealogists should consider the number of times information has been copied and the types of derivation a piece of information has undergone. The types of derivatives include: photocopies, transcriptions, abstracts, translations, extractions, and compilations.

In addition to copying errors, compiled sources (such as published genealogies and online pedigree databases) are susceptible to misidentification errors and incorrect conclusions based on circumstantial evidence. Identity errors usually occur when two or more individuals are assumed to be the same person. Circumstantial or indirect evidence does not explicitly answer a genealogical question, but either may be used with other sources to answer the question, suggest a probable answer, or eliminate certain possibilities. Compilers sometimes draw hasty conclusions from circumstantial evidence without sufficiently examining all available sources, without properly understanding the evidence, and without appropriately indicating the level of uncertainty.

Primary and secondary sources

In genealogical research, information can be obtained from primary or secondary sources. Primary sources are records that were made at the time of the event, for example a death certificate would be a primary source for a person's death date and place. Secondary sources are records that are made days, weeks, months, or even years after an event.

Standards and ethics

Organizations that educate and certify genealogists have established standards and ethical guidelines they instruct genealogists to follow.

Research standards

Genealogy research requires analyzing documents and drawing conclusions based on the evidence provided in the available documents. Genealogists need standards to determine whether or not their evaluation of the evidence is accurate. In the past, genealogists in the United States borrowed terms from judicial law to examine evidence found in documents and how they relate to the researcher's conclusions. However, the differences between the two disciplines created a need for genealogists to develop their own standards. In 2000, the Board for Certification of Genealogists published their first manual of standards. The Genealogical Proof Standard created by the Board for Certification of Genealogists is widely distributed in seminars, workshops, and educational materials for genealogists in the United States. Other genealogical organizations around the world have created similar standards they invite genealogists to follow. Such standards provide guidelines for genealogists to evaluate their own research as well as the research of others.

Standards for genealogical research include:

  • Clearly document and organize findings.
  • Cite all sources in a specific manner so that others can locate them and properly evaluate them.
  • Locate all available sources that may contain information relevant to the research question.
  • Analyze findings thoroughly, without ignoring conflicts in records or negative evidence.
  • Rely on original, rather than derivative sources, wherever possible.
  • Use logical reasoning based on reliable sources to reach conclusions.
  • Acknowledge when a specific conclusion is only "possible" or "probable" rather than "proven".
  • Acknowledge that other records that have not yet been discovered may overturn a conclusion.

Ethical guidelines

Genealogists often handle sensitive information and share and publish such information. Because of this, there is a need for ethical standards and boundaries for when information is too sensitive to be published. Historically, some genealogists have fabricated information or have otherwise been untrustworthy. Genealogical organizations around the world have outlined ethical standards as an attempt to eliminate such problems. Ethical standards adopted by various genealogical organizations include:

  • Respect copyright laws
  • Acknowledge where one consulted another's work and do not plagiarize the work of other researchers.
  • Treat original records with respect and avoid causing damage to them or removing them from repositories.
  • Treat archives and archive staff with respect.
  • Protect the privacy of living individuals by not publishing or otherwise disclosing information about them without their permission.
  • Disclose any conflicts of interest to clients.
  • When doing paid research, be clear with the client about scope of research and fees involved.
  • Do not fabricate information or publish false or unproven information as proven.
  • Be sensitive about information found through genealogical research that may make the client or family members uncomfortable.

In 2015, a committee presented standards for genetic genealogy at the Salt Lake Institute of Genealogy. The standards emphasize that genealogists and testing companies should respect the privacy of clients and recognize the limits of DNA tests. It also discusses how genealogists should thoroughly document conclusions made using DNA evidence. In 2019, the Board for the Certification of Genealogists officially updated their standards and code of ethics to include standards for genetic genealogy.

Extended family

From Wikipedia, the free encyclopedia
https://en.wikipedia.org/wiki/Extended_family

An extended family is a family that extends beyond the nuclear family of parents and their children to include aunts, uncles, grandparents, cousins or other relatives, all living nearby or in the same household. Particular forms include the stem and joint families.

Description

In some circumstances, the extended family comes to live either with or in place of a member of the immediate family. These families include, in one household or close proximity, relatives in addition to an immediate family. An example would be an elderly parent who moves in with his or her children due to old age. In modern Western cultures dominated by immediate family constructs, the term has come to be used generically to refer to grandparents, uncles, aunts, and cousins, whether they live together within the same household or not. However, it may also refer to a family unit in which several generations live together within a single household. In some cultures, the term is used synonymously with consanguineous family.

A stem family, a kind of extended family, first discussed by Frédéric Le Play, parents will live with one child and his/her spouse, as well as the children of both, while other children will leave the house or remain in it, unmarried. The stem family is sometimes associated with inegalitarian inheritance practices, as in Japan and Korea, but the term has also been used in some contexts to describe a family type where parents live with a married child and his or her spouse and children, but the transfer of land and moveable property is more or less egalitarian, as in the case of traditional Romania, northeastern Thailand or Mesoamerican indigenous peoples. In these cases, the child who cares for the parents usually receives the house in addition to his or her own share of land and moveable property.

In an extended family, parents and their children's families may often live under a single roof. This type of joint family often includes multiple generations in the family. Three to four generations stay together under a single roof. The joint family form a coherent group, follow common culture, have equal rights over property and celebrate all the festivals and functions of the family together. From culture to culture, the variance of the term may have different meanings. With globalization, increasing urbanization people have become more individualistic and consider family secondary.

Sociology

Often, it has been presumed that extended family groups sharing a single household enjoy specific advantages, such as a greater sense of security and belonging due to sharing a wider pool of members to serve as resources during a crisis, and more role models to help perpetuate desired behavior and cultural values. However, even in cultures in which adults are expected to leave home after marriage to begin their own nuclear-based households, the extended family often forms an important support network offering similar advantages. Particularly in working-class communities, grown children tend to establish their own households within the same general area as their parents, aunts, uncles, and grandparents. These extended family members tend to gather often for family events and to feel responsible for helping and supporting one another, both emotionally and financially.

While contemporary families may be considered more mobile in general than in the past, sociologists find that this has not necessarily resulted in the disintegration of extended family networks. Rather, technological aids such as the Internet and social networking sites such as Facebook are now commonly used to retain contact and maintain these family ties.

Particularly in the case of single-parent households, it can be helpful for extended family members to share a single household in order to share the burden of meeting expenses. On the other hand, sharing a household can present a disadvantage depending on the sizes and number of families involved, particularly when only a few members shoulder most of the responsibility to meet expenses for the family's basic needs.

An estimated 49 million Americans (16.1% of the total population) live in homes comprising three or more generations, up from 42 million in 2000. This situation is similar in Western Europe. Another 34 percent live within a kilometer of their children.

Around the world

In many cultures, such as in those of Asians, Middle Easterners, Africans, Indigenous peoples like Native Americans and Pacific Islanders, and Latin Americans and Caribbeans, even for Eastern Europeans and Southern Europeans (Orthodox/Catholic countries), extended families are the basic family unit. That is to say the modern western nuclear family is not the norm. Even in Western Europe, extended families (mostly of the stem type) were also clearly prevalent, England being a rare exception. In Britain and the United States, during the Industrial Revolution (approximately 1750 to 1900), more people lived in extended families than at any time before or since.

It is common for today's world to have older children in nuclear families to reach walking up to driving age ranges before meeting extended family members. Geographical isolation is common for middle-class families who move based on occupational opportunities while family branches "retain [their] basic independence". Some extended families hold family reunions or opportunities for gathering regularly, normally around holiday time frames, to reestablish and integrate a stronger family connection. This allows individual nuclear families to connect with extended family members.

Australian Aborigines are another group for whom the concept of family extends well beyond the nuclear model. Aboriginal immediate families include aunts, uncles and a number of other relatives who would be considered "distant relations" in the context of the nuclear family. Aboriginal families have strict social rules regarding whom they can marry. Their family structure incorporates a shared responsibility for all tasks.

Where families consist of multiple generations living together, the family is usually headed by the elders. More often than not, it consists of grandparents, their sons, and their sons' families in patriarchal and especially patrilineal societies. Extended families make discussions together and solve the problem.

Indian subcontinent

Historically, for generations South Asia had a prevailing tradition of the joint family system or undivided family. The joint family system is an extended family arrangement prevalent throughout the Indian subcontinent, particularly in India, consisting of many generations living in the same home, all bound by the common relationship. A patrilineal joint family consists of an older man and his wife, his sons and unmarried daughters, his sons’ wives and children. The family is headed by a patriarch, usually the oldest male, who makes decisions on economic and social matters on behalf of the entire family. The patriarch's wife generally exerts control over the household, minor religious practices and often wields considerable influence in domestic matters. Family income flows into a common pool, from which resources are drawn to meet the needs of all members, which are regulated by the heads of the family.

Recent trend in the United States

In the early stages of the twentieth century, it was not very common to find many families with extended kin in their household, which may have been due to the idea that the young people in these times typically waited to establish themselves and start a household before they married and filled a home. As life expectancy becomes older and programs such as Social Security benefit the elderly, the old are now beginning to live longer than prior generations, which then may lead to generations mixing together. According to results of a study by Pew Research Center in 2010, approximately 50 million (nearly one in six) Americans, including rising numbers of seniors, live in households with at least two adult generations, and often three. It has become an ongoing trend for elderly generations to move in and live with their children, as they can give them support and help with everyday living. The main reasons cited for this shift are an increase in unemployment and slumped housing prices and arrival of new immigrants from Asian and South American countries. According to the U.S. Census Bureau, there were 2.7 million grandparents raising their grandchildren in 2009. The dramatic increase in grandparent-headed households has been attributed to many factors including parental substance abuse. In 2003, the number of U.S. "family groups" where one or more subfamilies live in a household (e.g. a householder's daughter has a child. The mother-child is a subfamily) was 79 million. Two-point-six million of U.S. multigenerational family households in 2000 had a householder, the householder's children, and the householder's grandchildren. That's 65 percent of multigenerational family households in the U.S. So it is twice as common for a grandparent to be the householder than for adult children to bring parents into their home. The increase in the number of multigenerational households has created complex legal issues, such as who in the household has authority to consent to police searches of the family home or private bedrooms.

Besides the legal issues that multigenerational households could create, there are issues that may arise from households where the grandparents are the sole guardians. The Supporting Grandparents Raising Grandchildren Act was signed into law on July 7, 2018 after unanimously passing the U.S. House and Senate. It was first introduced in the Senate on May 10, 2017 by Senators Susan Collins (R-ME) and Bob Casey Jr. (D-PA). Out of this came The Supporting Grandparents Raising Grandchildren Advisory Council which will identify, promote, coordinate, and disseminate to the public information, resources, and the best practices available to help grandparents and other older relatives both meet the needs of the children in their care and maintain their own physical and mental health and emotional well-being. 

Mexico

Mexican society is composed of three-generational units consisting of grandparents, children, and grandchildren. Further close relationships are maintained with the progenitors of these families and are known as kin or "cousins". When one is born, they are born into two extended families, a kinship group of sometimes 70 people. The group traditionally acts as a cohesive unit, pooling resources and influence. The extended family also consists of spouses and siblings. This is in contrast to the two generational American nuclear family.

Some scholars have used the term "grand-family" to describe the close relationship between grandparents, children, and grandchildren in Mexican society. Larissa A. Lomnitz and Marisol Perez-Lizaur, for example, describe the grand-family as "the basic unit of family solidarity in Mexico", where basic family obligations between grandparents, children, and grandchildren include "economic support, participation in family rituals, and social recognition".

Economic background

The relative economic deprivation of racial and ethnic minorities leads to higher levels of extended family involvement; primarily because blacks and Latinos have less money and education than whites, they are more likely to give and receive help from kin. Having family on which one can rely is very important in times of economic hardship especially if there are children involved. Living in an extended family provides constant care for children and support for other members of the family as well. Analysis of the National Survey of Families and Households suggests there are differences between whites and other ethnic groups because of economic differences among racial groups: blacks and Latinos less often have the economic resources that allow the kind of privatization that the nuclear family entails. Extended kinship, then, is a survival strategy in the face of economic difficulties. Being able to rely on not only two parents but grandparents, aunts, uncles, brothers, and sisters helps to create a support system which in turn brings families closer together. Living in an extended family provides many things that a nuclear family does not.

The number of multigenerational households has been steadily rising because of the economic hardships people are experiencing today. According to the AARP, multigenerational households have increased from 5 million in 2000 to 6.2 million in 2008. "There's no question that with some ethnicities that are growing in America, it is more mainstream and traditional to have multigenerational households. We're going to see that increasing in the general population as well," says AARP's Ginzler. While high unemployment and housing foreclosures of the recession have played a key role in the trend, Pew Research Center exec VP and co-author of its multigenerational household study Paul Taylor said it has been growing over several decades, fueled by demographic and cultural shifts such as the rising number of immigrants and the rising average age of young-adult marriages. The importance of an extended family is one that many people may not realize, but having a support system and many forms of income may help people today because of the difficulties in finding a job and bringing in enough money.
