Francis Seymour, of Sherborne, Dorset
Seymour was the second son of Sir Edward Seymour, 5th Baronet and his wife Letitia Popham. In 1728, he succeeded to the estates of his paternal great-uncle Henry Seymour Portman MP, which included Sherborne House. He married on 30 July 1728 his cousin Elizabeth Popham, Dowager Lady Hinchingbrooke (died 20 March 1761), daughter of Alexander Popham, of Littlecote, Wiltshire, MP, and great granddaughter of Colonel Alexander Popham.

At the 1734 British general election he was elected in a contest as MP for Marlborough on the Bruce interest. He did not stand again in 1741. On all recorded occasions, he voted against the Administration of Walpole.
