clan

A clan is a group of people united by actual or perceived kinship
and descent. Even if lineage details are unknown, a clan may claim descent from a founding member or apical ancestor who serves as a symbol of the clan's unity. Clans, in indigenous societies, were not endogamous: their members could not marry one another.
Clans preceded more centralized forms of community organization and government, and have existed in every country. Members may identify with a coat of arms or other symbol.
