King Alexander III of Scotland (1241–1286), King of Scots, only son of Alexander II by his second wife Marie de Coucy
Marie de Coucy was the daughter of Enguerrand III, Lord of Coucy (d.1242), builder of the Château de Coucy, in Picardy (c.1220s), which probably served as a model for Dirleton.
Always diplomatic, Coucy managed to maintain both his allegiance to the King of France and to his English father-in-law during the period of intermittent armed conflict between England and France known as the Hundred Years' War.
Raoul II, Lord of Coucy (died 1250) was a son of Enguerrand III and his wife Maria of Oisy.
