Clan Bruce (Scottish Gaelic: Brùs) is a Lowlands Scottish clan. It was a Royal House in the 14th century, producing two kings of Scotland (Robert the Bruce and David II of Scotland), and a disputed High King of Ireland, Edward Bruce.
The surname Bruce comes from the French de Brus or de Bruis, derived from the lands now called Brix, Normandy, France. There is no evidence to support a claim that a member of the family, 'Robert de Brix', served under William the Conqueror during the Norman Conquest of England. This notion is now believed to have originated in unreliable lists, derived from the later Middle Ages, of people who supposedly fought at the Battle of Hastings.
