Genealogy
In the United States, pedigree per se has not been crucial in determining status or in transferring property, but race formerly served as a great social divider (e.g., blacks were formerly enslaved in the South and were later denied their civil rights and prohibited from marrying whites in many states). In more limited situations, genealogy has had a degree of importance in the United States: Some societies limit membership to descendants of a particular group of ancestors; the Mormons collect genealogical information for religious purposes and have established a large Family History Library; and some families keep careful genealogical records and stage periodic reunions.
Since the 18th cent. genealogy has developed into a subsidiary academic discipline, serving sociology, history, medicine, and law. Libraries often have departments of genealogy, where volumes used in genealogical research are kept (e.g., passenger ship lists, immigration records, family genealogies, etc.); many historical societies also have such libraries. Many genealogical materials, such as those compiled by the Mormons, are now available for research on the World Wide Web.
