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.[1]
In 1489, on the death of his cousin Margaret Coker, the wife of Sir Reynold Stourton, Seymour inherited the Somerset manors of West Bower in Bridgwater, Moorland in North Petherton, and Cokers in Wembdon.[2]
Marriage and children
Seymour married twice. His first marriage was to Elizabeth Darrell (born c. 1451), daughter of Sir George Darrell (died c. 1474) of Littlecote, Wiltshire, by his first wife Margaret Stourton (born c. 1433), a daughter of John Stourton, 1st Baron Stourton, and of Margery or Marjory Wadham. By Elizabeth Darrell, Seymour had four sons and four daughters,[2][3] including:
