Robert Bruce, Lord of Liddesdale
Sir Robert Bruce, Lord of Liddesdale was an illegitimate son of King Robert the Bruce and an unknown mother. He was knighted and awarded the royal arms at the Battle of Bannockburn.
His father made him Lord of Liddesdale after William II de Soules was found guilty of treason at the Black Parliament of 1320. It has been suggested that he may have been the father of Thomas Bruce, 1st Baron of Clackmannan, but there is no clear evidence for this.
Faced with Edward Balliol's invasion of Scotland, he and Donnchadh IV, Earl of Fife carried out an unsuccessful attempt on 6 August 1332 to repel the landing at Kinghorn in Fife. He then quarrelled with the regent, Donald II, Earl of Mar.
He was killed leading a charge at the Battle of Dupplin Moor on 11 August 1332.
