Seymour, a second cousin of the 11th duke of Somerset and the son of a groom of the bedchamber to George III, was detained in France, 1803-14, when he was ‘one of the very few Englishmen exempted from close confinement’, having obtained ‘permission to remain at large ... from the Emperor Napoleon’. He returned to take up his inheritance, ‘without having lost English sympathies by a long forced residence abroad’.
He divided against Catholic relief, 6 Mar. 1827. Affirming his hostility to Catholic claims, which ‘it would be found impossible to ram ... down the throats of the people of England’, he nevertheless announced his intention of supporting Canning’s coalition ministry ‘until that question came to be discussed’, 2 May. He may have been the H. Seymour who voted with government against the Penryn election bill, 7 June. He presented petitions for repeal of the Test Acts from Taunton, 20 June 1827, and Fulwood, Somerset, 19 Feb., which suggests that it was possibly not he who voted against that measure, 26 Feb. 1828. He divided against Catholic claims, 12 May. He supported an individual’s petition for compensation for property lost during the French Revolution, 23 June, observing that ‘my father was robbed of his property in 1790’ and ‘I shall always consider that government owes me £3,000’. He presented a Taunton anti-slavery petition, 30 June. He may have voted for the corporate funds bill, 10 July 1828. The volte face performed by Seymour’s patron Lethbridge on Catholic emancipation placed him in an awkward position. In February 1829 Planta, the Wellington ministry’s patronage secretary, originally listed Seymour among those ‘opposed to the principle’, but his name was later scored through and added to the list of Members who would side ‘with government’. His name did not appear in the published division lists of 6, 30 Mar., but a local newspaper was authorized to state that he had voted for emancipation on the first occasion.
Seymour devoted the later years of his life to consolidating his estate in Wiltshire, where he laboured to ‘fulfil the duties of an English gentleman and a Christian’.
