Genealogy
Genealogy (from Greek: , , "generation"; and , , "knowledge") is the study of families and the tracing of their lineages and history. Genealogists use oral traditions, 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.
Some scholars differentiate between genealogy and family history, limiting genealogy to an account of kinship, while using "family history" to denote the provision of additional details about lives and historical context.
Overview
Hobbyist 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 work for companies that provide software or online databases. 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 social 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 are able to prove descent from a participant of the Salem Witch Trials or who choose simply to support the group.
Genealogists and family historians often join family history societies, where novices can learn from more experienced researchers. Such societies may also index records to make them more accessible, and engage in advocacy and other efforts to preserve public records and cemeteries.
