==Biography==
Waltheof of Allerdale was an 11th- and 12th-century Anglo-Saxon noble, lord of Allerdale in modern Cumbria. Brother of Dolfin of Carlisle and Gospatric of Dunbar, Waltheof son of Gospatric, Earl of Northumbria. Both Waltheof and his brother Gospatric witness Earl David's Glasgow Inquest 1113 x 1124, and Waltheof also attests some of David's charters as king of the Scots later. The account of Waltheof and his family in Cumbrian monastic cartularies (St Bees and Wetheral), says that he gave land in Allerdale to his three sisters, Octreda, Gunhilda and Maud.
