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)
During this period after the 2nd Earl's execution, Walter was permitted to continue his studies at Oxford, and matriculated from Queen's College, Oxford on 16 November 1604 at the age of 13. During this time he apparently drew closer to his half-brother, Robert Devereux, the legal heir of the 2nd Earl and future 3rd Earl who also was suffering from these losses. Throughout the remainder of Walter's life, he would remain a retainer of Robert, and when the title was restored in July 1603 Walter's fortunes rose as well.
