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)
About 1240 William was mentioned in Walter de Lacy's charter describing the grant of L30 rent in Holme Lacy (Herefordshire) and the village of Hay (Ireland) to Simon de Clifford for the manor of Yarkhill (Herefordshire). Devereux also witnessed the grant of Katherine, daughter of Walter Lacy of Land in Cofham to Acornbury Priory. During Easter 1244 Margery, widow of Walter de Lacy, sued William Devereux for one third of 2 mills in Hereford, which she claimed as part of her dower.
