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.

On 10 November 1388 Walter Devereux witnessed John de Cornewaile of Kinlet’s grant of warranty for life to Cornewaile's mother of two thirds of the manor of Ashton, Herefordshire, if she should outlive his father, Sir Brian. On 28 June 1390 he was place on a commission of Oyer and terminer in addition to his role as Justice of the Peace for Herefordshire. On 15 July Devereux was on the commission conducting the inquiry post-mortem of John Hastings, 3rd Earl of Pembroke, who had died before coming of age. He was directed to inquire what lands had been held in dower at the death of the earl's widowed mother, Anne Manny, on 3 April 1384, and the widow of Aymer de Valence, 2nd Earl of Pembroke, Marie de St Pol, on her death 16 March 1377.
