The Oxford Dictionary of National Biography states that Richard de Burgh (d. 1243) was justiciar of Ireland, and that he was [2]
… the son of William de Burgh (d. 1206) and his wife, the daughter of Domnall Mór Ó Briain, king of Thomond, who married in 1193. The de Burgh family came from Norfolk. William, the brother of Hubert de Burgh, justiciar of England from 1215 to 1232, became involved in Ireland as a result of the visit of John, lord of Ireland, in 1185. … He died in 1206 and Richard, his heir, became a ward of the crown until 1214 when he received his inheritance. …
De Burgh died early in 1243 when serving on Henry III's expedition to Poitou. He had three sons: Richard, his first heir, who died in 1248; Walter de Burgh (d. 1271), his eventual heir, who in 1263 was created earl of Ulster; and William, who died in 1270 and whose descendants came eventually to control most of Connacht.
