gens

n. group of aristocratic Roman families having the same name and descended from a common ancestor on the male side (in ancient Rome); clan with common male ancestor; (Lating) family

In ancient Rome, a gens (pl. gentes) was a clan, caste, or group of families, that shared a common name (the nomen) and a belief in a common ancestor. In the Roman naming convention, the second name was the name of the gens to which the person belonged. The term has also been used to refer to families within a clan system in other contexts, including tribal clans.
