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 1641)
Walter Devereux was sent in 1608 to a riding academy in Angers, France. He had returned by May 1613 when the divorce suit of his half-brother, Robert Devereux, began, and over the next several months was manipulated by the King and his powerful allies at the expense of Essex and the Devereux family's reputation. Essex's wife, Frances Howard, and the King's faction forced the divorce to be granted as nullity requiring impotence to permit her remarriage to the King's favorite. The ongoing slurs and insults drove Essex to challenge his brother-in-law, Henry Howard, on 20 August to a duel, and Walter would serve as one of Essex's seconds. The King would not allow the duel to go forward. On 25 September the verdict of nullity was granted, and the next day the King called a special Court of Honor to stop the duel. The Court interviewed the seconds including Walter Devereux, but the testimony was altered. Essex refused to sign the report indicating they were false. Walter signed with Richard Oubeley the following "Declaration of Essex’s Seconds":
