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)
Walter Devereux was born in 1173, the son of John Devereux. His father died in 1187 possibly from involvement in the de Braose campaigns in Wales and France. The Pipe Rolls of 1190 show 8 pounds and 13 pence of oblations due the king's court were pardoned for the lands of John Devereux in Herefordshire. As Walter was under-age his lands and 2 castles (including Lyonshall) were taken into the hands of the king and placed in the possession of the sheriff of Hereford, William de Braose. Devereux participated in the expansion of the Norman holdings in Ireland, and in 1210 Walter Devereux was listed as having been responsible to John (fitzJohn) Marshal for 20 shillings of fees for the maintenance of soldiers ‘beyond the water that is called Stiuthe,' and 2 marks for those at Carrickfergus in Ireland
