General Notes

Per Cokayne's "Complete Peerage (Despenser, pp. 259-261):  This Hugh was at the parl. of Oxford, 1258, he was one of the 12 elected by the barons to
redress grievances and treat with the council of KING HENRY III. Appointed
Justiciar of England 1260.  Attended Montfort's parl. of 1063.  Was at the
battle of Lewes 1264.  In 1265 he was appointed an arbiter between the Earls of Leicester [Simon de Montfort (RIN 2884*)] and Gloucester [GILBERT DE CLARE (RIN 726)]. He was prominent in the rebellion against KING HENRY III and died alongside Simon de Montfort at the Battle of Eversham in 1265.

Hugh Despencer, taking part with the barons, was nominated justiciary of England under the baronial power in the 44th of Henry III [c. 1270]. After the battle of Lewes he was one of those to whom the custody of the captive monarch was committed and he was then entrusted with the castles of Orford, in Suffolk, and Devises, in Wilts, and Barnard Castle, in the bishopric of Durham. He was summoned to parliament on 14 December 1264 as "Hugh le Despencer, Justiciar AngliE," and lost his life under the baronial banner at the battle of Evesham. His lordship m. Aliva, dau. of Philip Bassett of Wycombe, co. Bucks, and afterwards 1st wife of Roger Bigod, Earl of Norfolk, by whom he left at his decease, August, 1265, Hugh, and Alianore m. to Hugh de Courteney, father of Hugh, 1st Earl of Devonshire. After the forfeiture and decease of Lord Despencer, his widow Aliva, for her father's sake, found such favour from the king that she was enabled to retain a considerable proportion of the property and, at her death in the 9th of Edward I, it devolved on the payment of a fine of 500 marks upon her son, Hugh Despencer, senior, so called to distinguish him from his son who bore the designation of Hugh Despencer, junior.
