Richard Óg de Burgh, 2nd Earl of Ulster and 3rd Baron of Connaught, called The Red Earl, was one of the most powerful Irish nobles of the late 13th and early 14th centuries and father of Elizabeth, wife of King Robert the Bruce of Scotland.

Elizabeth de Burgh was the second wife and the only queen consort of Robert the Bruce. Elizabeth was born sometime around 1289, probably in what is now County Down or County Antrim in Ulster, the northern province in Ireland. She was the daughter of one of the most powerful Norman nobles in the Lordship of Ireland at that time, Richard Óg de Burgh, the 2nd Earl of Ulster, a member of the noble dynasty, the House of Burgh and a close friend and ally to King Edward I of England.
