Clan Douglas
Alexander Douglas-Hamilton, 16th Duke of Hamilton, and 13th Duke of Brandon is heir to the chiefdom of the house of Douglas, but he cannot assume the title of chief since the Lord Lyon King of Arms requires him to assume the single name Douglas. Note that the Duke of Hamilton is the Chief of Clan Hamilton. For a list of the historic chiefs of Clan Douglas see: Earl of Douglas until 1455 and Earl of Angus for after 1455.
