John Seymour (c. 1450 – 26 October 1491) of Wulfhall, of Stalbridge, of Stinchcombe and of Huish, all in Wiltshire, England, was warden of Savernake Forest and a prominent member of the landed gentry in the counties of Wiltshire, Somerset and Dorset. He was the grandfather of Jane Seymour (c. 1508–1537), the third wife of King Henry VIII, and was thus great-grandfather of King Edward VI. Origins Seymour was the eldest of the three sons of John Seymour (c. 1425–1463), Knight of the Shire for Wiltshire and High Sheriff of Wiltshire, by his wife Elizabeth Coker (born about 1436), daughter of Sir Robert Coker of Lydeard St Lawrence, Somerset. Seymour's father predeceased his own father John Seymour (died 1464), and thus in 1464, Seymour succeeded to his grandfather's estates. Career As warden of Savernake Forest, Seymour tried to restore the ancient boundaries of his bailiwick. At the forest eyre at Marlborough in 1464, and at the following eyre in 1477, he made wild claims. In June 1485 he was able to obtain letters patent to establish "the bounds of the Forest of Savernake before the perambulation of Henry III", and at the eyre of 1491 he used this to claim that the Farm and West bailiwicks of the forest extended from the Ridgeway and Pewsey in the west to the edge of Hungerford in the east.
