The second son of Charles II and his principal mistress, Barbara Palmer, countess of Castlemaine (later duchess of Cleveland), there is some doubt as to the precise date of Henry Fitzroy’s birth, which occurred between 2 and 28 Sept. 1663. He was initially not acknowledged by his royal father, who doubted his resemblance to other members of his brood. It was thus not until 1672 that he was formally recognized, and in August of that year he was created earl of Euston when he was contracted to marry Lady Isabella Bennet, daughter of the earl of Arlington (both parties being underage).
Grafton spent much of the remainder of his youth in France, and in 1676 he was entrusted to the ambassador to Paris, Ralph Montagu, later duke of Montagu, to be schooled in French language and etiquette.
Although Grafton was the recipient of a number of grants from the king and expected to inherit his father-in-law’s estates in Suffolk, it was designed early on that he should make his way in the world as a sailor, and following his marriage he was entrusted to the tutelage of the veteran mariner, Sir John Berry.
The final years of Charles II saw Grafton appointed to a number of military posts. In the winter of 1682 he was made vice-admiral of England in succession to Prince Rupert, duke of Cumberland, and he appears to have used his new position to frustrate the ambitions of Admiral Arthur Herbert, later earl of Torrington, to be appointed to the admiralty commission.
The death of Charles II threatened to curtail Grafton’s continuing preferment, but he retained his places under his uncle and served as lord high constable at the coronation. Although he was noted as being abroad at a call of the House on 26 May 1685, the following day he was marked present on the attendance list, though he was not formally introduced. He was then absent for the remainder of the session. The outbreak of the rebellion against King James led by Grafton’s half-brother, James Scott, duke of Monmouth, offered Grafton the opportunity to demonstrate his loyalty to the new regime, and he was at the forefront of those involved in suppressing the rebellion, during which he was noted for his bravery both at Sedgemoor and in an earlier action where he had found his advance troop ambushed by some of Monmouth’s musketeers.
While his military career went from strength to strength, Grafton’s marriage appeared on the brink of collapse by the autumn of 1685. The breakdown in relations between Grafton and his duchess probably owed something to Arlington’s death that summer. Grafton may also have been disappointed at his failure to be appointed lord chamberlain in succession to his father-in-law.
Grafton was one of the peers to try Henry Booth, 2nd Baron Delamer (later earl of Warrington), in January 1686.
The following year found Grafton involved in another dispute, this time with George Berkeley, earl of Berkeley, probably over rights in Nonsuch Park, where Berkeley was the keeper. Having been denied entry to the park by some of Berkeley’s servants, Grafton was successful in prosecuting them for assault, but he was then indicted in the court of king’s bench for forcible entry.
In 1687 Grafton was listed among those believed to favour the king’s intention to repeal the Test Act; he was also included in another list of about May noting those sympathetic to the king’s policies. Grafton’s apparent willingness to acquiesce in the new regime’s religious policy was further demonstrated in July when he agreed to introduce the papal nuncio at Windsor following the refusal to do so by Charles Seymour, 6th duke of Somerset.
Although the king now entertained serious doubts about his nephew’s dependability, Grafton was granted leave to serve as a volunteer in the fleet preparing for the Dutch invasion.
Although Grafton and Churchill had been deep in the army plot, they were as little trusted in William of Orange’s camp as in that of the king and were rewarded with the thankless task of attempting to restore order to King James’s disbanded forces.
Grafton was present at a meeting convened at Windsor to determine what should be done with the king.
Grafton’s decision to divide against those wishing to award the crown to William and Mary was undoubtedly the principal cause of his removal from office, but he also seems to have been a victim of the new king’s reluctance to trust those at the head of the English armed forces.
Absent at the opening of the second session, Grafton registered his proxy with Sidney Godolphin, Baron (later earl of) Godolphin, on 23 Oct. which was vacated by his resumption of his seat on 23 November. He was thereafter present on 29 per cent of all sitting days during which he was named to two committees. On 29 Nov. Grafton again appealed to have his privilege upheld over the arrest of his servant Robert Terkill by the Suffolk attorney, Thomas Sawyer of Langham. On 5 Dec. Grafton entrusted his proxy to Godolphin once more, which was vacated by his return to the House on 13 January. It is possible that his absence was occasioned by attendance on his regiment in Ireland and rumours circulated at this time that he was shortly to have ‘some considerable command given to him.’
Grafton found his interest in Suffolk squeezed in the elections for the new Parliament, and he was unsuccessful in securing the return of his nominees, Sir Robert Davers‡ and Sir John Playters for the county seats.
Grafton may have been an unruly man prone to acts of violence but his death was widely lamented.
