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 c. 1383)
Walter Devereux, as a retainer of the Humphrey de Bohun, 7th Earl of Hereford, served with him in France. In May 1369 he was granted protection and appointed an attorney for 1 year while overseas in France. Devereux was with the forces John of Gaunt led to Calais, and participated in his raids into northern France. He was at the siege of Harfleur in October 1369 that had to be abandoned due to an outbreak of plague and dysentery. He fought at the Battle of the Ford of Blanchetaque on the Somme River, and returned with the army to Calais by mid-November.
