Genealogists collect oral histories and preserve family stories to discover ancestors and living relatives. Genealogists also attempt to understand not just where and when people lived but also their lifestyle, biography, and motivations. This often requires - or leads to - knowledge of antique law, old political boundaries, immigration trends, and historical social conditions.
Genealogists and family historians often join a Family history society where novices can learn from more experienced researchers, and everyone benefits from shared knowledge.
Even an unsuccessful search for ancestors leads to a better understanding of history. The search for living relatives often leads to family reunions, both of distant cousins and of disrupted families. Genealogists sometimes help reunite families separated by war, immigration, foster homes, and adoption. The genealogist can help keep family traditions alive or reveal family secrets.
