Fitzroy continued to sit for Bury on the family interest. He had supported Pitt on the Regency, but left no mark in the Parliament of 1790, apart from being listed ‘doubtful’ on the question of repeal of the Test Act in Scotland in 1791. He served in Flanders in 1793-4. In the latter year his mother left him £60,000.
No vote of Fitzroy’s is known before 1812; but he was listed a supporter of Pitt’s second ministry in September 1804 and July 1805. In 1806 he was listed among ‘staunch friends’ of the abolition of the slave trade. He was a defaulter on the call of the House, 2 Mar., and did not vote on the question of the dismissal of the Grenville ministry in April 1807. Nevertheless, Lord Buckingham thought he should be listed among their friends, rather than doubtful.
Fitzroy retired from the House in 1818. On the death of his second wife in 1810 he had retreated to his Northamptonshire estate, where he enjoyed a reputation as a philanthropist. He died 20 Dec. 1829. He is not to be confused with his cousin Gen. Charles Fitzroy (1762-1831).
