[7] His father had gone over to the Baronial cause towards the end of the Second Barons' War, but by this time Hugh was established in his own right and remained loyal to the king.
Following his father's death probably at the Battle of Evesham, Hugh Devereux was granted safe conduct by the king on 4 May 1266 lasting through midsummer to allow him to come to court.
[9] He was identified as Lord of Chanston on 8 December 1293 when recorded as taking a loan of 4 pounds and 7 shillings from Richard, son of Roger de Orleton, a merchant of Herefordshire.
[10] On 9 March 1299 Richard Swinefield, Bishop of Hereford, requested that the King order the sheriff of Hereford (Miles Pichard) to eject armed men led by Hugh Devereux and his sons, and Richard Dansey who had taken possession of Turnastone Church, and the chapel and rectory of Saint Leonard's in county Herefordshire.
The land in the village of Aynaldestone had been part of the agreed upon dower for Hugh's mother, Isabel, upon her marriage to Nicholas II Devereux as his first wife.
