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 1402)
Walter Devereux represented Herefordshire in Parliament on 20 January 1401. On 29 April he was placed on a commission to arrest John fitzPieres and Maurice ap Meweryk. On 16 May Devereux was appointed Sheriff of Herefordshire, appointed Justice of the Peace for Herefordshire, and tasked with suppressing lawlessness in South Wales, Bergeveny, Herefordshire, and the March of Wales. As the insurrection spread through the marches, Devereux was assigned on 26 August to inquire into the murder of Thomas Stannesbache of Bromyard, and the wounding of William Ranves at Bromyard. On 11 May 1402 Walter Devereux was appointed to make a proclamation of Henry IV's intention to govern well in Herefordshire. Shortly after he set out with Sir Edmund Mortimer to fight the rebels.
