Yorkist side at the
Battle of Hexham in 1464. In 1469, he was made Steward of the
Duchy of Cornwall for life. He was made
Earl of Wiltshire on 5 January 1470[2] by King Edward IV, and was briefly arrested under
Warwick's government and prevented from attending the Parliament of November 1470 (he was one of six Yorkist nobles not to receive a summons).[3]
He did act for some time as a diplomat, working with the Earl of Northumberland to deal with ambassadors of
James III of Scotland about national grievances.[5]
Personal life
He married Constance Green, daughter of Sir Henry Green of
Drayton HouseNorthamptonshire[5] and Margaret de Ros. They only had one child,
Edward, who succeeded him as Earl of Wiltshire, although during the latter's minority he was kept as a ward of the King, meaning revenues from his estates were paid to the Crown.[6]
