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, 7th Baron Ferrers of Chartley
As a member of the Council of Wales, Walter Devereux was probably with Edward V when he was declared king following the sudden death of Edward IV on 9 April 1483. It would be expected that he accompanied Edward as he set out for London, and was probably among the retinue that was dismissed when Richard, Duke of Glouucester intercepted them at Stony Stratford, Buckinghamshire on 29 April. Following the deposition of Edward V and crowning of the Duke as Richard III on 6 July 1483, Walter Devereux transferred his allegiance to the new king and was confirmed as Justice of the Peace for Herefordshire, Gloucestershire, Shropshire, and Hertfordshire. On 1 August Walter Devereux of Ferrers; his son, Sir John Devereux of Ferrers; and others were assigned in Herefordshire to assess and appoint collectors of the subsidies granted by the last Parliament from aliens (with the exception of the nations and merchants of Spain, Brittany, and Almain). Devereux attended Parliament on 23 January 1484, and was assigned to raise an army on 1 May 1484 in Hertfordshire, and Herefordshire. He was rewarded with the grant of Cheshunt manor, Hertfordshire, for life on 12 August; and assigned to investigate certain treasons and offenses committed by William Colingbourne late of Lidyard, Wiltshire; and John Turburville late of Firemayne, Dorset.
