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.

In October 1462 Margaret of Anjou landed and raised a Lancastrian rebellion in northern England. Devereux accompanied King Edward on an expedition to the north in November 1462, which put the rebellion down by January 1463. Walter attended Parliament on 29 April 1463 where he was rewarded with an exemption from the crown's Act of Resumption revoking various gifts and grants.
