In August 1780 Fitzwilliam’s brother, Earl Fitzwilliam, was approached by Charles Anderson Pelham about the choice of a candidate at Grimsby. Fitzwilliam immediately wrote to his uncle, Lord Rockingham, suggesting that they should propose George Fitzwilliam and defray the expenses of his election between them. Rockingham refused, thinking it too costly and risky a venture, and no other seat was found for Fitzwilliam at the general election.
In November 1783 Lord Fitzwilliam planned to nominate his brother at the York by-election, but was informed that a considerable part of the Rockingham Club were ‘violent associators’ for parliamentary reform, and had it ‘fresh in their minds that Mr. Fitzwilliam voted against the reform bill’.
George Fitzwilliam died 6 May 1786.
