A descendant of John de Charlton, the first Sir Thomas de Charlton, died in 1448 whereupon Swakeleys passed to his son, also named Sir Thomas, who became Speaker of the House of Commons and member of parliament (MP) for Middlesex. He died in 1465, at which point his son Sir Richard became owner of the manor. Sir Richard was killed fighting on the side of Richard III during the Battle of Bosworth Field in 1485. The victor of the battle, Henry VII, named him in his Act of Attainder, though he granted Sir Richard's wife Elizabeth a life interest in the manor. However, Sir Thomas Bourchier was subsequently granted the manor of Swakeleys and Covelhall (Cowley). Upon Sir Thomas' death in 1510, the manor passed to Sir John Peeche as his executor. Sir John had no children, so Swakeleys passed to the Earl of Devon, Henry Courteney in 1521. The Earl granted a licence to control Swakeleys to Sir William Fitzwilliam in 1531, who was acting as trustee for Ralph Pexall.
