Barons le Despencer, Fourth Creation (1357)
Again without the reversal of the previous attainders, another descendant was summoned in 1357, by modern usage creating a fourth barony. With the reversal of the attainders of Lord Hugh the elder (first creation) and Lord Hugh the younger (second creation) in 1398, the hereditary right to these earlier baronies vested in the holder of this fourth barony.
Edward le Despencer, 1st Baron le Despencer (1336–1375)
Thomas le Despencer, 2nd Baron le Despencer (1373–1400) (benefactor of the reversal of the attainder of first and second creations in 1398; attainted 1400)
The first, second, and fourth creations lay under attainder from 1400. The attainder was reversed in 1461, but the hereditary right had fallen into abeyance from 1449. This abayance was settled in 1604 in favor of Mary Fane, with precedence dating from the Parliament of 1264.
The le Despenser family originated from the lords of Gomiécourt in north-eastern France. Henry le Despenser's grandmother Eleanor de Clare was a granddaughter of Edward I of England.

Henry's great-grandfather Hugh le Despenser, 1st Earl of Winchester (1262–1326) and grandfather Hugh Despenser the Younger (1286–1326), who was a favourite of Edward II, were both exiled and later executed after the rebellion of Queen Isabella and her lover Mortimer against Edward II of England. Hugh le Despenser had become Edward II's adviser, holding power until the king's defeat at the Battle of Bannockburn, but he was later restored to favour. His son was appointed the king's chamberlain and enjoyed a still larger share of royal favour. The barons were hostile to the Despensers, due to their acquired wealth and perceived arrogance, and in 1321 they were banished. Their sentences were soon afterwards annulled and from 1322 they played an important role in the governing of the country, but in 1326 Isabella acted against them and both men were tried and executed.
In 1375, Despenser's nephew Thomas le Despenser, 1st Earl of Gloucester succeeded his father Edward. Thomas was captured and killed following the attempt to restore Richard II in the 1399-1400 Epiphany Rising.
