Carteret’s family originated in Jersey, a cadet branch of the de Carterets of St Ouen’s Manor, one of the most prominent families on the island. Carteret’s grandfather, Sir George Carteret‡, had made the move to England following his resolute service in the royal cause during the Civil War and Interregnum. Although he ended his career under a cloud following investigations into financial mismanagement, Sir George was rewarded shortly before his death in 1680 with the promise of elevation to the peerage.
Despite his grandfather’s reputed wealth, Carteret appears to have succeeded to a comparatively modest estate.
In 1687, possibly while he was still abroad, Carteret was marked doubtful in a list of peers and their likely attitudes to James II’s policies. At the revolution he rallied to Princess Anne, who journeyed via Carteret’s manor at Hawnes in Bedfordshire on her way to Nottingham.
Carteret was close to his father-in-law, Bath, whose political allegiances up until the moment of revolution had been solidly Tory. In the aftermath of revolution, however, Bath switched his allegiances, and the young Carteret followed his lead. He voted in favour of inserting the words declaring William and Mary king and queen on 31 Jan., and the same day he entered his dissent to the Lords’ refusal to declare the throne ‘vacant’. On 4 Feb. he again voted in support of the Commons’ employment of the term ‘abdicated’ and the same day dissented once more when the House failed to concur with that, or with the phrase ‘that the throne is thereby vacant.’
Still absent at the opening of the second (1689-90) session of the Convention, Carteret was excused at a call of the House on 28 Oct. 1689. He took his seat two days later but was thereafter present on just 27 of the 73 sitting days, during which time he was named to five committees. He resumed his seat for the new Parliament on 27 Mar. 1690, after which his level of attendance improved. He was present on 74 per cent of all sitting days and was named to just four committees. On 13 May he protested at the resolution not to allow the Corporation of London more time to be heard by their counsel during the debates over the bill to restore the City’s charter. He resumed his place four days after the opening of the following session on 6 Oct. 1690. On that day, he voted against the discharge of James Cecil, 4th earl of Salisbury and Henry Mordaunt, 2nd earl of Peterborough, from their imprisonment in the Tower. Carteret’s attendance thereafter declined dramatically, with him present on a mere four days during the 76 day session.
Carteret’s attendance increased during the 1691-2 session. Present on almost 70 per cent of all sitting days, he was named to seven committees. Towards the end of the year he was included in a list compiled by William George Richard Stanley, 9th earl of Derby, as one of those peers who had opposed Derby’s previous attempt to be restored to various lands in Wales sold during the Interregnum. Carteret had been abroad and underage at the time so perhaps the list was indicative of Carteret’s intentions towards Derby’s renewed proposal, which was thrown out at second reading in January 1692.
Carteret resumed his seat for the 1694-5 session on 7 Dec. 1694 but he attended a mere three days before quitting the session and the House for the last time. He died intestate the following year on 22 Sept. 1695 aged just 28 and was succeeded by his young son, John Carteret, as 2nd Baron Carteret (later earl of Granville).
