The record of genealogical work may be presented as a "genealogy" or a "family history". In the narrow sense, a "genealogy" traces the descendants of one person, whereas a "family history" traces the ancestors of one person,[4][5] but the two terms are often used interchangeably.[6] A family history may include additional biographical information, family traditions, and the like.[3]
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.[7] Genealogy research is also performed for scholarly or forensic purposes. - Wikipedia
