Walter Devereux, 7th Baron Ferrers of Chartley
Walter Devereux was with the army as Edward IV marched north, and fought in the victory at the Battle of Towton on 29 March 1461, where he was knighted. On 8 July Devereux was appointed Justice of the Peace, and place on the Commission of Array for Herefordshire, Gloucestershire, and Shropshire to raise troops to stamp out Lancastrian resistance in Wales. He was also placed on a commission of Oyer and terminer to inquire into all treasons, insurrections and rebellions in South Wales, and granted the authority to receive submission into the king's peace of rebels. In September Walter Devereux met with the king and William Herbert at Ludlow Castle where they were assigned to take into the king's hands all the castles, lordships, manors, land and possessions of the late Humphrey, Duke of Buckingham, in South Wales. On 30 September 1461, Herbert and Devereux captured Pembroke Castle. On 16 October Herbert and Devereux defeated the Lancastrians under Pembroke and Exeter at the Battle of Twt Hill, effectively ending resistance in Wales. Walter Devereux attended Parliament on 4 November 1461, but was back in Wales for the capture of Denbigh Castle in January 1462.
Walter Devereux (died 1641)
The Earl acknowledged his son and made financial arrangements on his behalf with an addendum to his will in July 1595: "Walter Devereux the base and reputed sonne of the said Robt Erle of Essex, begotten of the body of Eliz: Southwell." The intent of the deed is thought to have been the granting of Essex House to Walter Devereux, but there is no evidence this disposition actually occurred. His only reported manor was that of Lamphey in Pembrokeshire, which comprised just 721 acres and yielded a little over £203 in rents each year. He sold Lamphey manor to Richard Cuny in November 1618, whereupon his half-brother, Robert, 3rd earl of Essex, bestowed upon him the lease of Lamphey rectory. The lack of adequate means was probably the principal cause that Devereux spent most of his adult life in Essex's household in Staffordshire and Westminster, and although he persistently described himself as being ‘of Lamphey’ there is no evidence to suppose that he ever lived there.
