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 (born 1173)
About 1186 Walter had witnessed with his father the land grant of Maud de Hagarnel to the priory of Brecon. About 1190 Devereux granted 12 acres of land near Berrington (Hereford) to the same priory ‘for the love he bore his lord, William de Braose the younger.’ This identifies Walter Devereux as a member of the military retinue of the Braose family. Devereux also witnessed the grant of land by William de Bradfelde of lands in Bradfield, Petercroft, Laneglege, lands near Mara, Estlege, and in Weteroft near the chapel to the priory of Brecon. In 1211, Walter Devereux was listed as having held 1/2 knight's fee of the honor of Brecon.
