John de Burgh

John de Burgh (1286–1313) was the eldest son and heir of Richard Óg de Burgh, the Red Earl of Ulster. On 30 September 1308 he married Elizabeth de Clare, sister of Gilbert de Clare, Earl of Gloucester; his own sister Maud married Gilbert the same year, sealing a double alliance.

Elizabeth joined him in Ireland in 1309 and on 17 September 1312 gave birth to William Donn, the future Earl of Ulster. John was killed in a minor skirmish at Galway on 18 June 1313, leaving the infant William as heir.
