A descent group of Caere and Vulci that is known as early as 630 to 620 BC for two inscriptions of possession on impasto jars in a tomb from San Paolo at Caere. Later occurrences are from Hellenistic monumental tombs at both Caere (Tomb of the Alcove) and Vulci (Tomb of Bulls). In the latter tomb, the family can be traced through four generations from Vel the founder. The family thus appears to have started in Caere and moved also to Vulci, where it engaged in successful intermarriage, surviving well into the first century BC.
