Gille Ruadh was the Galwegian leader who led the revolt against King Alexander II of Scotland. His birth, death date and origins are all unknown. Upon Alan, Lord of Galloway's death in 1234, Galloway was left without a legitimate feudal heir. Alexander II had decided to partition the lordship between the Anglo-Norman husbands of Alan's three living daughters, Roger de Quincy (married to Ela), John de Balliol (married to Derborgaill) and William de Forz (married to Cairistiona).
