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 (died 1402)
On 8 February 1391 Devereux conducted an inquiry into the alienation of the manor of Eaton Tregoes, Herefordshire. On 20 January John and Julian Kirby of La Verne sold for 100L Kimbolton manor, Huntingdonshire; and 2 carucates of land, 12 acres of meadow, and 13 shillings of rent in Laysters, Weston, Mappenore, Leominster, and Aston in Herefordshire to Walter Devereux. A writ was issued in Herefordshire on 17 February 1392 for Thomas, son of Llewelyn le Taillour, for not appearing to answer Walter Devereux regarding a debt of 40L. On 1 March 1392 Devereux was assigned to raise troops in Hertfordshire to resist an invasion in case of war after the expiration of the current truce.
