A Whig in politics, Grafton sported a rather gruff persona, which accorded well with his principal passion as a committed fox hunter and student of horseflesh.
Unlike most of Charles II’s illegitimate sons, Grafton’s father, the first duke, had been established with a considerable estate. This included the right to the reversion of the manor of Grafton in Northamptonshire and grants out of the excise and post office as well as the succession to the property of his father-in-law, Arlington, in Suffolk and Norfolk.
Early on singled out for advancement at court, Grafton was appointed master of the horse to Princess (later Queen) Anne’s son, William, duke of Gloucester, in 1698. At the close of that year he was packed off on a foreign tour.
Grafton’s concern to secure his inheritance may have been connected with a scheme on foot towards the close of that summer for his marriage to one of the daughters of Colonel Godfrey, brother-in-law to John Churchill, duke of Marlborough, but in the event nothing came of the match. The following spring (March 1703) Grafton was granted a pass to travel overseas to join Marlborough as a volunteer at the siege of Bonn and was commissioned as a captain of horse for the campaign.
Grafton joined parties of Whig peers dining at the Queen’s Arms in Pall Mall on two occasions in March 1704.
Grafton took his seat just over a fortnight after the opening of the new Parliament on 12 Nov. 1705, after which he was present on over 56 per cent of all sitting days. The following month he divided with the majority in concluding the Church to be in no danger.
Coinciding with his efforts in the 1708 elections, Grafton was said once more to be contemplating matrimony. The latest target of his interest was said to be a nonconformist called Mrs. Knight, worth £70,000. A report of April had noted that he was ‘very assiduous’ about her even to the extent of attending Nonconformist meetings on Sunday afternoons. Although his wooing failed to have the desired effect, his interest in ‘Widow Knight’ seems not to have diminished and a number of years later he was again thought to be on the point of marrying her.
Grafton was employed on a minor diplomatic assignment in September when he was sent to convey the queen’s compliments to the queen of Portugal on her arrival at Portsmouth.
Grafton supported the candidacy of Sir Philip Parker‡ for Suffolk in the 1710 elections, though both seats were again carried by Tory candidates (one of them being Hanmer). With neither of the sitting members prepared to stand again at Thetford he appears to have resolved not to involve himself there after the expenses incurred in the previous contest.
Grafton came under assault from the Northamptonshire Tory members in August over his proposed appointment as chief ranger of Whittlewood forest. In a letter to Oxford (as Harley had since become) Sir Justinian Isham‡ and Thomas Cartwright‡ pointed out the undesirability of the appointment given the duke’s interest in the forest already and the influence he would be able to bring to bear on the elections in both the county and in the neighbouring corporations of Buckingham and Brackley.
Grafton treated Prince Eugene of Savoy to a sumptuous entertainment at his London residence early in January 1712.
Grafton was one of a dozen or so young lords who were noted to have abandoned the opposition at the beginning of June 1712 over the Whig-sponsored motion to amend the vote of thanks to the queen following her speech laying out the terms of the peace. Among those deserting with him were Dorset and Cornwallis. Grafton’s association with the latter continued on 13 June when Cornwallis registered his proxy with the duke, which was vacated by the close of the session.
Grafton attended the House on five of the prorogation days between the close of the second session and opening of the third in April 1713. In advance of the new session he was listed by Jonathan Swift as a likely opponent of the ministry and on 9 Apr. he voted with the minority over the proposed amendment to the address in reply to the queen’s speech.
Grafton took his seat in the new session on 16 Feb. 1714, after which he was present on over 70 per cent of all sitting days. He covered his absence from the House between 11 and 31 Mar. by registering his proxy with Cornwallis on 13 March. Cornwallis then registered his own proxy with Grafton on 27 Mar. (before Grafton had resumed his seat), which was in turn vacated by Cornwallis’ return to the House on 5 April. Cornwallis’ mistake was presumably caused by a clerical error but technically invalidated both proxies. Grafton was forecast by Daniel Finch, 2nd earl of Nottingham, as opposed to the Schism bill in May. The same month (on 12 May) he registered his proxy with his Suffolk neighbour, Hervey, which was vacated by his resumption of his seat on 26 May. On 15 June he subscribed his protest at the passing of the Schism bill and on 28 June he registered his proxy with Francis Godolphin, 2nd earl of Godolphin, vacated by his return to the House two days later. On 8 July he subscribed a further protest at the resolution not to make representation to the queen stating that the benefits of the Asiento had been obstructed by certain individuals’ efforts to obtain personal advantages from the contract.
Grafton was present on just four days of the brief session that met in the wake of Queen Anne’s death in August, but on 2 Aug. he received Godolphin’s proxy, which was vacated two days later. The Hanoverian succession proved a turning point in Grafton’s career. Although he was initially named one of the gentlemen of the new king’s bedchamber, he was put out in 1717, but then benefited by Walpole’s re-emergence after 1722 and was rewarded with appointment as lord lieutenant of Ireland and then as lord chamberlain, a post he held until his death. During this period he was closely associated with the old corps Whigs, led by Thomas Pelham Holles, duke of Newcastle.
Grafton died on 6 May 1757 as a result an injury sustained earlier in the year from a fall. In his will he requested that he be buried ‘in the most private manner as the rest of my family have been’. Grafton fathered nine children with his wife before her death in childbirth in 1726, in addition to at least one illegitimate child, Charles Fitzroy Scudamore‡, who was returned at Thetford in successive elections after 1733 on his father’s interest.
