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 26 April 1385 he was appointed to a Commission of array for Herefordshire to prepare for an imminent French invasion. Devereux participated in Richard II's expedition to Scotland in the summer of 1385, and probably was knighted during this time. On 9 November 1385 Walter was appointed Justice of the Peace, and to a commission of Oyer and terminer for Herefordshire along with his liege, Thomas of Woodstock. He would continue to hold the position of Justice of the Peace through 1399.
