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 18 June 1394 Walter Devereux was again placed on a commission of Oyer and Terminer for Herefordshire. On 7 August he was granted clause volumus (protection) for one half year while accompanying Richard II to Ireland, and on 28 September nominated Roger Wigmore and Thomas Oldcastle as his attorneys in his absence. Devereux was probably serving in the retinue of Thomas of Woodstock who accompanied the king. The army landed and marched towards Kilkenny undergoing harassment by Irish forces the entire way. After suffering heavy losses, Richard II agreed to negotiate, and brought the army to Dublin by December. The king abruptly returned to England to deal with the Lollard threat, and left part of the army behind under the nominal leadership of the under-age, Roger Mortimer, 4th Earl of March.
