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.
Walter Devereux, 7th Baron Ferrers of Chartley
On 26 June 1460 the earls of Warwick and Salisbury landed at Sandwich, and raised a Yorkist rebellion. They marched on London, and captured Henry VI at the Battle of Northampton on 10 July 1460. Walter Devereux was appointed to arrest and imprison any in Herefordshire resisting the rebellion, Richard of York returned to England and Walter Devereux attended Parliament on 7 October as a knight of the shire for Herefordshire. The Duke became Protector of the Realm again on 31 October, and Devereux was granted a general pardon.
