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's grandmother, Lettice Dudley Countess of Leicester, wrote to Robert Cecil, 1st Earl of Salisbury, in 1608 to assist in arranging his marriage to "Lady Stallenge’s daughter"." This is most likely the daughter of Lady Florence Stallenge. She had two daughters, Margaret and Elizabeth by Sir Christopher Kenn. After he died in 1593, Florence married her second husband, Nicholas Stallenge. The daughter most likely referred to in the letter was Margaret who ended up marrying Sir William Guise in 1608, and died before 1612 after bearing him a single son and heir. Her younger sister, Elizabeth, would marry a few years later to Sir John Paulet. There is no clear evidence that Walter Devereux married.
