Seymour Conway was returned for his father’s borough of Orford in 1790. A friend of the Prince of Wales, he had acted with opposition since 1785 and did so again on Pitt’s Russian policy, 12 Apr. 1791, 1 Mar. 1792, contenting himself as before with a silent vote. He was also listed favourable to repeal of the Test Act in Scotland in 1791. On the list of Portland Whigs compiled in 1792 his brother Hugh was docketed ‘Prince of Wales’ and he was queried. He was thought of for recruitment to Windham’s ‘third party’ in February 1793. At any rate like the rest of his family he became well disposed to government, which raised his father to the marquessate in July 1793. He did not stand for re-election in 1796, having meanwhile inherited £500 p.a., and a legacy of £6,000 from his father, which his eldest brother doubled.

Before his marriage, the Queen thought him shy. He parted from his wife. In later years he was ‘a very eccentric character and led a wandering life, travelling over the country on foot in the dress of a sailor; living in wretched inns at little expense ...’ He died 31 Jan. 1837.
