A member of the cadet branch of the duke of Grafton’s family, Fitzroy was the younger son of the 2nd Baron Southampton, who died when he was only three years old, leaving him as the heir presumptive to his elder brother Charles. They were raised by their ‘austerely Calvinist’ mother, who regularly administered severe physical punishments. Such a childhood left an indelible imprint and produced ‘a certain timidity’ in his character, though he ‘stood well over six feet, with thick black hair, bright blue eyes and a ready smile’.
Fitzroy voted against ministers on the Dublin election controversy, 23 Aug. 1831. He divided to preserve the existing rights of freemen under the reform bill, 27 Aug., and in his maiden speech three days later argued against robbing ‘these honest and incorrupt voters’ of the franchise, citing the reduction of the electorate that would occur in Great Grimsby and the desire of freemen to pass on their rights to their children, which they valued ‘as strongly as the higher classes do, the desire of transmitting their fortunes and their titles to their posterity’. He was in the minority for preserving the rights of non-resident freemen that day. He divided against the passage of the reform bill, 21 Sept. He was one of only seven Members who voted for Waldo Sibthorp’s complaint of a breach of privilege by The Times, 12 Sept., when he also voted for inquiry into how far the Sugar Refinery Act could be renewed with due regard to the interests of the West Indian producers. He voted against the second reading of the revised reform bill, 17 Dec. 1831. When Great Grimsby’s place in schedule B came before the House, 23 Feb. 1832, he followed Loughborough in defending the borough and its reputation, declaring that not only had its population increased significantly since 1821, but that it was likely soon ‘to become one of the most important seaports in the kingdom’. He predicted that the bill would hand control of the borough to Yarborough, and in response to Robert Waithman, who suggested that Great Grimsby was ‘notoriously corrupt’, insisted that neither he nor his colleague had ‘ever made a single promise of money to any voter’. He voted against the enfranchisement of Tower Hamlets, 28 Feb., the third reading of the reform bill, 22 Mar., and the second reading of the Irish measure, 25 May. He divided against ministers on the Russian-Dutch loan, 26 Jan., 12 July 1832.
At the 1832 general election Fitzroy unsuccessfully contested Northampton as a Conservative. He was defeated at Lewes in 1835, but returned at a by-election in 1837 and sat until 1841, when he was beaten but seated on petition. He remained a Member until his death. Initially a Conservative and a supporter of free trade, he gravitated to the Liberal party.
