Roger de Quincy, 2nd Earl of Winchester
Roger de Quincy, 2nd Earl of Winchester ( – 25 April 1264), hereditary Constable of Scotland, was a nobleman of Anglo-Norman and Scottish descent who was prominent in both England and Scotland, at his death having one of the largest baronial landholdings in the two kingdoms. Early life The de Quincy family, originating from the village of Cuinchy in Artois, had been prominent in England and Scotland from about 1130. Roger, second son and eventual heir of Saer de Quincy, 1st Earl of Winchester, and his wife Margaret, younger daughter of Robert de Beaumont, 3rd Earl of Leicester, probably joined his father on the Fifth Crusade, during which the elder de Quincy fell sick in Egypt and died. Since Roger's older brother Robert had died a few years earlier, he inherited his father's estates on his return, but was not recognised as earl until his mother died in 1235. Career He married a major heiress, Helen of Galloway, the eldest of the three daughters of Alan, Lord of Galloway. On her father's death in 1234, he acquired her share of the paternal inheritance, which consisted of the hereditary office of Constable of Scotland and one-third of the lordship of Galloway.
