The Political History of England, Vol II, George Burton Adams Longmans Green and Co, 1905, Ch I p12:
 "While William waited at Barking, other English lords in addition to those who had already acknowledged him came in and made submission. The Norman authorities say that the earls Edwin and Morcar were chief of these, and if not earlier, they must have submitted then. Two men, Siward and Eldred, are said to have been relatives of the last Saxon king, but in what way we do not know. Copsi, who had ruled Northumberland for a time under Tostig, the brother of Harold, impressed the Norman writers with his importance, and a Thurkill is also mentioned by name, while `many other nobles' are classed toghether without special mention. Another great name which should probably be added to this list is that of Waltheof, Earl of Northampton and Huntingdon, of distinguished descent and destined later to an unhappy fate. All of these the kingreceived most kindly. He accepted their oaths, restored to them all their possessions, and held them in great honour."
From Alfred to Henry III 871-1272, Christopher Brooke, 1961, The Norton Library History of England, p85:
"Tostig, Harold's brother, had been Earl of Northumbria since old Siward's death in 1055. But the Northumbrians owed no natural allegiance to a son of Godwin, and they proved intractable subjects. In 1065 they rebelled and forced the King to appoint Morcar,brother of Edwin, Earl of Mercia, and grandson of Cnut's earl, Leofric, in Tostig's place...
