Walter Devereux (1411–1459)
Following the death of Edmund Mortimer, 5th Earl of March, on 18 January 1425, Richard, 3rd Duke of York inherited his estates along the Welsh Marches. This brought Walter Devereux into the retinue of the Duke, and he remained his loyal supporter throughout the War of the Roses. Devereux had been knighted by 22 September 1429 when he first represented Herefordshire in Parliament. He probably was in attendance on the Duke when he travelled with Henry VI to France for his coronation on 16 December 1429. On his return Devereux represented Herefordshire again in Parliament on 16 January 1430. He was listed on the subsidy rolls for Herefordshire of 12 January 1431 as holding his 1/3 of half a fee in Byford.
William Devereux (1219–1265)
In 1262 Llywelyn ap Gruffyd attacked the Welsh Marches again. On 22 December 1262 the king commanded William Devereux to appear with arms and horses on 9 January 1263 at Hereford to counter this invasion. On 24 January 1263 William Devereux was further commanded to come on 5 February 1263 to Hereford. Once there William and the other lords summoned were to divide the gathered forces for the defense of their castles and lands, and to insure that their castles were kept in good repair. On 3 March 1263 the English fought the Welsh at the Battle of Abergavenny. On 15 April 1263 Prince Edward specifically begs his father to command Will d’Evereus’ to “quod in castro suo de le Hales” and “moram faciet ac partes suas viriliter defendat.“ This translates to say, “that in his castle of Lyonshall he should stay and vigorously defend his estates.” On 25 May 1263 the king again commanded William Devereux to appear with horses and arms on 1 August 1263 at Worcester for a campaign against Llywelyn. For his ongoing faithful service the King ordered William be given a gift of 2 deer from the forests of Salop on 13 September 1263.
