Known only from inscriptions on coinage, where his name appears singly as ‘ANDO’ or ‘ANDOCO’, and jointly on one issue as ‘TAS ANDO’ in which it is assumed that his name appears with that of his overlord, Tasciovanus. The distribution of these coins suggest that Andocos or Andocoveros ruled over a territory on the western flank of the Catuvellauni, and was issuing coin towards the end of the reign of Tasciovanus (c.15BC-c.10AD) at the turn of the first century AD. Suggested variatons of his name include Andocos or Andocoveros.
