Waltheof was high-reeve or ealdorman of Bamburgh (fl. 994). He was the son of Osulf I. His name is Scandinavian and implies that he had Viking ancestors. It remained in his family when Earl Siward married his great-granddaughter and named his son Waltheof. This son of Siward became Waltheof, Earl of Northumbria.
