Fitzroy, known by the courtesy title of the earl of Euston, was the eldest son of the fourth duke of Grafton, owner of extensive estates in Norfolk, Suffolk and Northamptonshire.
Euston had been returned to the Commons by his father for Bury St. Edmunds in 1818 and again in 1826. He generally supported the Whigs and in 1830 had voted steadily for various parliamentary reform proposals.
Euston sought a return to the Commons in August 1834 when he offered as a Reformer for a vacancy at Thetford caused by the death of his youngest brother Lord James Henry Fitzroy. Although the Grafton interest was strong enough to return one member, a group of local tradesmen, dismayed at the family’s lack of financial outlay in the borough, sought to bring forward their own candidate, but a requisition asking a local barrister to stand against them eventually came to nothing, leaving Euston to be elected unopposed.
Despite such statements, Euston again deserted his party on a major issue when he voted for the Conservative Charles Manners Sutton for speaker, 19 Feb. 1835. However, he immediately returned to the Whig fold, dividing in opposition to Peel on the address, 26 Feb. 1835, and for Irish church appropriation, 2 Apr. 1835. Thereafter he steadily supported the Melbourne ministry’s Irish policy, though his attendance was generally poor. Like his father, he made little impact in the Commons and is not known to have spoken in the post-Reform era. His select committee work appears to have been limited to that on the handloom weavers’ petition.
Re-elected without opposition in 1837, Euston, on the rare occasions when he troubled the division lobbies, continued to give silent support to the Whig government. Although a devout Anglican, he voted against John Plumptree’s motion condemning the Maynooth grant, 23 June 1840. He opposed Peel’s motion of no confidence in the Whig ministry, 4 June 1841.
At the 1841 general election Euston was opposed for the first time by a second Conservative candidate. The last to begin a canvass, Euston ran a lacklustre campaign and was repeatedly attacked with the accusation that his family did not represent the best interests of the Thetford’s ‘independent’ electors.
Euston succeeded as the fifth duke of Grafton on his father’s death in September 1844. In the Lords he made occasional and brief interventions on some of the main issues of the day, including railway legislation and distress in Ireland. Hitherto, the dukes of Grafton had been hereditary receivers-general of the profits of the seals in the courts of the queen’s bench and common pleas, but in 1845 the office was abolished and substituted with a pension of £843 per annum by an Act of Parliament (7 & 8 Vict. c. 34).
Grafton died at Wakefield Lodge in March 1863.
