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.

George Devereux was the son of Sir George Devereux of Sheldon Hall, Warwickshire and the nephew of Walter Devereux, Viscount Hereford. He played a leading part in Montgomeryshire politics and was a ‘recruiter’ M.P. for Montgomery in the Long Parliament (6 April 1647). He was suspended as a ‘ delinquent ’ the following May, but signed the Montgomeryshire declaration for Parliament on 20 May 1648. After the king's execution he remained in retirement till he began to sit on county committees in 1657 and accepted office as sheriff in 1658. Haslam attributes the building of the brick house shown in John Ingleby’s watercolours to him around 1640, but it could also be after the Civil War.
