Robert de Umfraville, Earl of Angus

Robert de Umfraville, 8th Earl of Angus (c. 1277 – 1325) was an Anglo-Norman baron in Northumberland and the eighth Earl of Angus.

He was the second son of Gilbert de Umfraville and Elizabeth Comyn, daughter of Alexander Comyn, Earl of Buchan.

He was more than thirty years old at his father's death. He adhered to Edward II both against Scots and barons, and was regularly summoned to the English parliaments as Earl of Angus. He fought at the Battle of Bannockburn, and was taken prisoner after the battle by Robert Bruce, but soon released. Though formerly in opposition to the Despensers, he sat in judgment on Thomas of Lancaster. Bruce deprived him of his Scottish estates and title, and before 1329 the real earldom had been vested in the House of Stuart, from whom it passed in 1389 to a branch of the Douglases.

Robert married twice. His first wife was Lucy, sister and heiress of William of Kyme, whose considerable estates in Yorkshire and Lincolnshire, including the castle of Kyme, passed thus to the Umfravilles. By her he had a son Gilbert and a daughter Elizabeth. By his second wife, Eleanor, he had two sons, Robert and Thomas.
