[3] His grandmother, Alice Grandison, died shortly after the birth of his father, and his grandfather married a second time to Lucy Burnell.
[b] His grandfather spent his life struggling to regain control of the lands forfeited by Stephen's great-grandfather who had died in rebellion at the Battle of Evesham in 1265, and were subject to the Dictum of Kenilworth.
[12] It is probable that de Bohun's defiant actions in support of baronial rights may have contributed to an unfavourable disposition by King Edward I towards the Devereux family.
[13] The sheriff of Herefordshire was ordered to determine if Sir William Devereux, Lord of Lyonshall, or his heirs held the castle.
[14] In June 1308 Tuchet requested 30 pounds compensation for damages and losses caused by the attacks executed by Stephen Devereux and 4 others.
As the Baron and his second wife were both alive and tenants-for-life, any action on behalf of Stephen was not supported by common law or Statute (which only gave right of recovery for alienation by a tenant-in-dower).
[19] As later the Despenser War played out, Devereux was also probably with Humphrey de Bohun when he was killed at the Battle of Boroughbridge on 16 March 1322.
[20] Although Stephen was in the party opposing the king's favorites, the Devereux of Bodenham bore a grudge against Mortimer that had its roots in his being granted their lands under the Dictum of Kenilworth described above.
The Despencer War also caught up with William Tuchet who was executed along with Bartholomew de Badlesmere in 1322 following the Battle of Boroughbridge.
His death brought Lyonshall Castle back into the King's hands as Baron Devereux's widow was still alive, and Badlesmere's heir was a minor.
[g] Stephen Devereux, like his cousin, lacked enough royal favor to regain Lyonshall during his lifetime, but remained a key retainer of the de Bohun family.
By 1340, Stephen had gained enough royal trust to be assigned on 20 April the task of collecting the ninth of lambs, fleeces, and sheaves in Herefordshire granted by Parliament to pay for the King's military actions on the continent.
Also his nephew, John Devereux of Whitchurch Maund, would rise through his close relationship with the Black Prince to finally regain the barony and Lyonshall Castle.
