Osulf I of Bamburgh

Oswulf was ruler of Bamburgh and subsequently, according to later tradition, commander of all Northumbria under the lordship of King Eadred of England. He is sometimes called "earl" or "high reeve", though the precise title of the rulers of Bamburgh is unclear. By the twelfth century Oswulf was held responsible for the death of Northumbria's last Norse king, Eric of York, subsequently administering the Kingdom of York on behalf of Eadred.
