After the Norman Conquest, Eadulf's son Osulf briefly held the earldom of northern Northumbria in 1067 until he too was killed, succeeded by Uhtred's grandson by his third marriage, Gospatric, who was Earl of Northumbria from 1068 to 1072 before being forced to flee to Scotland. His replacement was Ealdred's maternal grandson, Waltheof II, who was deprived and in 1076 executed for treason. The murder of his Norman replacement, William Walcher, Bishop of Durham, by Uhtred's descendant Eadulf Rus led William the Conqueror to send an army northwards to harry the region again.
