Henry Grey, 4th Baron Grey of Codnor (1435 – April 1496) was an English nobleman of the fifteenth century. Having initially supported the House of Lancaster during the Wars of the Roses, he later gave his allegiance to the victorious King Edward IV.[1] Despite a record of conflict with other members of the nobility, he enjoyed the confidence of the King, who appointed him Lord Deputy of Ireland, an office in which he was a notable failure. He retained the favour of two later monarchs, Richard III and Henry VII, both of whom made him grants of land.
