The Berkeley family is an ancient English noble family. It is one of only five families in Britain that can trace its patrilineal descent back to an Anglo-Saxon ancestor (the other four being the Arden family, the Swinton family, the Wentworth family, and the Grindlay family).[1][2][3] The Berkeley family retains possession of much of the lands it held from the 11th and 12th centuries, centred on Berkeley Castle in Gloucestershire, which still belongs to the family.
