Gosset belonged to a French Huguenot family who had fled to Jersey after the revocation of the Edict of Nantes. His great-uncle Isaac Gosset (1713-99) settled in London and made a name for himself as the creator of exquisite wax models, specializing in cameo portraits; his son, also Isaac (1745-1812), attended Oxford University and became a celebrated biblical scholar and bibliophile.
He was an occasional attender who gave general support to Lord Liverpool’s ministry. He almost certainly divided against economies in revenue collection, 4 July 1820. He voted in defence of ministers’ conduct towards Queen Caroline, 6 Feb. 1821. He divided against Catholic relief, 28 Feb. He voted against repeal of the additional malt duty, 3 Apr., parliamentary reform, 9 May, the omission of arrears from the duke of Clarence’s grant, 18 June, and Hume’s economy and retrenchment motion, 27 June. On the army estimates, 25 May 1821, he observed that there had been no recent increase in the pay of inspectors of the Channel Islands militia.
Gosset was taken up by the 1st marquess of Anglesey, who appointed him his secretary as master-general of the ordnance in Canning’s ministry and employed him as his private secretary during his first spell as Irish viceroy under the duke of Wellington in 1828.
