Affeton is a former historic manor in Devon. It was at one time also a parish with its own parish church, but was later merged into the parish of West Worlington. The manor house was almost entirely demolished in the Civil War, the only part left standing was the gatehouse, which fell into ruin. A large farmhouse known as "Affeton Barton" was soon after built over the foundations and cellars of the manor house. The ruinous gatehouse was converted in 1868-9 to a shooting box for the use of the Stucley family of Hartland Abbey and Moreton House, Bideford, and became known thereafter as "Affeton Castle".
The descent of Affeton is as follows:
The de Affeton family are the earliest recorded holders of the manor of Affeton, from which they took their name. They held the manor from the feudal barony of Plympton, the barons of which were the Courtenay Earls of Devon and feudal barons of Okehampton.
The Stucley (alias Styuecle, Stukeley, etc.) family, a junior branch of which inherited Affeton on the marriage of Hugh Stucley, Sheriff of Devon in 1448, to Catherine de Affeton, daughter and sole heiress of John de Affeton by his wife Elizabeth Manningford, originated at the manor of Great Stukeley in Huntingdonshire.
Sir John Wadham (died 1502) married, as his second wife, Elizabeth Stucley, daughter of Hugh Stucley. Their son and heir was Sir Nicholas Wadham (died 1542) of Edge, Branscombe, Devon and of Merryfield, Ilton in the county of Somerset. Sir Nicholas Wadham was grandfather to Nicholas Wadham (1531-1609) who, with his wife Dorothy Wadham, co-founded Wadham College, Oxford.
