The 3rd Earl of Ulster married, before 16 November 1327 (by a Papal Dispensation dated 1 May 1327), Maud of Lancaster, daughter of Henry, 3rd Earl of Lancaster and Maud Chaworth. They had only one surviving child, Elizabeth, Countess of Ulster, who was 13 months old when he was murdered. She married Lionel of Antwerp, third son of Edward III of England.
In November 1332, at Greencastle, near the mouth of Lough Foyle, he had his cousin Sir Walter Liath de Burgh starved to death. In revenge, Sir Walter's sister, Gylle de Burgh, wife of Sir Richard de Mandeville, planned his assassination.
In June 1333, he was killed by de Mandeville, Sir John de Logan, and others. The Annals of the Four Masters noted that "William Burke, Earl of Ulster, was killed by the English of Ulster. The Englishmen who committed this deed were put to death, in divers ways, by the people of the King of England; some were hanged, others killed, and others torn asunder, in revenge of his death."
His widow, Maud, fled to England, where she remarried, was again widowed in 1346, and then became an Augustinian Canoness at Campsey Priory, where she is buried. Upon his death, the various factions of the de Burghs, now called Burke, began the Burke Civil War for supremacy.
