A family tree, also called a genealogy or a pedigree chart, is a chart representing family relationships in a conventional tree structure. More detailed family trees, used in medicine and social work, are known as genograms.
Genetic testing, also known as DNA testing, is used to identify changes in DNA sequence or chromosome structure. Genetic testing can also include measuring the results of genetic changes, such as RNA analysis as an output of gene expression, or through biochemical analysis to measure specific protein output. In a medical setting, genetic testing can be used to diagnose or rule out suspected genetic disorders, predict risks for specific conditions, or gain information that can be used to customize medical treatments based on an individual's genetic makeup. Genetic testing can also be used to determine biological relatives, such as a child's biological parentage through DNA paternity testing, or be used to broadly predict an individual's ancestry. Genetic testing of plants and animals can be used for similar reasons as in humans, to gain information used for selective breeding, or for efforts to boost genetic diversity in endangered populations.
Frome is a town and civil parish in Somerset, England, on uneven high ground at the eastern end of the Mendip Hills and on the River Frome, 13 miles (21 km) south of Bath. The population of the parish was 28,559 in 2021.
Genetic genealogy is the use of genealogical DNA tests, i.e., DNA profiling and DNA testing, in combination with traditional genealogical methods, to infer genetic relationships between individuals. This application of genetics came to be used by family historians in the 21st century, as DNA tests became affordable. The tests have been promoted by amateur groups, such as surname study groups or regional genealogical groups, as well as research projects such as the Genographic Project.
The Genographic Project, launched on 13 April 2005 by the National Geographic Society and IBM, was a genetic anthropological study that aimed to map historical human migrations patterns by collecting and analyzing DNA samples. The final phase of the project was Geno 2.0 Next Generation. Upon retirement of the site, 1,006,542 participants in over 140 countries had joined the project.
Somerton and Frome was a constituency in Somerset represented in the House of Commons of the UK Parliament.
A genealogical DNA test is a DNA-based genetic test used in genetic genealogy that looks at specific locations of a person's genome in order to find or verify ancestral genealogical relationships, or to estimate the ethnic mixture of an individual. Since different testing companies use different ethnic reference groups and different matching algorithms, ethnicity estimates for an individual vary between tests, sometimes dramatically.
Cheddar Man is a human male skeleton found in Gough's Cave in Cheddar Gorge, Somerset, England. The skeletal remains date to around the mid-to-late 9th millennium BC, corresponding to the Mesolithic period, and it appears that he died a violent death. A large crater-like lesion just above the skull's right orbit suggests that the man may have also been suffering from a bone infection.

23andMe Holding Co. is an American personal genomics and biotechnology company based in South San Francisco, California. It is best known for providing a direct-to-consumer genetic testing service in which customers provide a saliva sample that is laboratory analysed, using single nucleotide polymorphism genotyping, to generate reports relating to the customer's ancestry and genetic predispositions to health-related topics. The company's name is derived from the 23 pairs of chromosomes in a diploid human cell.
DNAPrint Genomics was a genetics company with a wide range of products related to genetic profiling. They were the first company to introduce forensic and consumer genomics products, which were developed immediately upon the publication of the first complete draft of the human genome in the early 2000s. They researched, developed, and marketed the first ever consumer genomics product, based on "Ancestry Informative Markers" which they used to correctly identify the BioGeographical Ancestry (BGA) of a human based on a sample of their DNA. They also researched, developed and marketed the first ever forensic genomics product - DNAWITNESS - which was used to create a physical profile of donors of crime scene DNA. The company reached a peak of roughly $3M/year revenues but ceased operations in February 2009.
MyHeritage is an online genealogy platform with web, mobile, and software products and services, introduced by the Israeli company MyHeritage in 2003.

The first internet website went live in 2003.
Bennett C. Greenspan is an American businessman. His business ventures have covered industries from real estate to the .com boom. Though he has mainly worked in the fields of photography and genetic testing, he is best known for his pioneering work in genetic genealogy.
The ancestral background of presidents of the United States has been relatively consistent throughout American history. With the exception of Martin Van Buren and perhaps Dwight D. Eisenhower, every president has ancestors from the British Isles, which in turn makes many of them distantly related to one another. John F. Kennedy was of pure Irish descent, Van Buren was of Dutch lineage; and Eisenhower was of German and Swiss heritage. Barack Obama is the only president to have ancestry from outside Western Europe; his paternal family is of East African ancestry. He is also believed to be a direct descendant of John Punch, a colonial-era slave born in modern-day Cameroon. Despite speculation, there is no evidence that any of the United States’ presidents have had any Indigenous American ancestry.
African American genealogy is a field of genealogy pertaining specifically to the African American population of the United States. African American genealogists who document the families, family histories, and lineages of African Americans are faced with unique challenges owing to the slave practices of the Antebellum South and North. These challenges rise from a range of events, including name changes following the American Civil War, the act of separating families for sale as slaves, lack of issued birth or death records for slaves, etc.
