Earl of Sutherland is a title in the Peerage of Scotland. It was created circa 1230 for William de Moravia. The Earl of Sutherland is also the Chief of Clan Sutherland. The original line of earls of Sutherland had the surname "de Moravia" although they sometimes used the surname "Sutherland", taken from their hereditary title. The name de Moravia meant "of Moray" or "of Murray". The de Moravias who were Earls of Sutherland and chiefs of Clan Sutherland shared their paternal ancestry with the chiefs of Clan Murray who were Earls and later Dukes of Atholl. However the de Moravias of Sutherland were the senior line of the family.
