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 c. 1383)
On 26 May 1380 Walter Devereux and his liege, Thomas of Woodstock, were appointed Justice of the Peace for Herefordshire. On 22 June 1380 he was granted protection and appointed an attorney for 1 year while overseas in France serving in the company of Thomas of Woodstock, Earl of Buckingham. In July Woodstock led an army across the channel to Calais to bring support to John IV, Duke of Brittany in his resistance to Charles V of France. The army marched east of Paris where it confronted Philip the Bold at Troyes, but the French refused battle and the two armies marched away. On 16 Sep 1380 Charles V died, and the French defense was thrown into disarray. Thomas of Woodstock led a chevauchée westward, and in November laid siege to Nantes. In January 1381 the Duke of Brittany reconciled with the new French King, Charles VI, and Woodstock was forced to abandon the siege due to dysentery and the collapse of his alliance.
