He was born in about 1650, the eldest son of Sir Philip Carteret, 1st Baronet (1620–1675) (Philippe de Carteret III), the 4th Seigneur of Sark, by his wife Anne des Augres (1566–1644),[1] daughter of Abraham Dumaresq Seig des Augres.
As the Sark court refused to allow an Anglican to preside, in 1675 Philippe requested the British crown to dissolve the court, which having been achieved by an Order in Council in 1675, he instituted in its place a jurisdiction composed of a Seneschal, Greffier and Prevot.
Carteret married Elizabeth Carteret (1663–1717),[2] a daughter of Sir Edward De Carteret, Seigneur De Trinity, Gentleman Usher of the Black Rod during the reign of King Charles II[3] and First Gentleman Usher Daily Waiter in Ordinary to the King,[4] by his wife Elizabeth Johnson.
[5] By his wife he had one son: Upon his death in 1693 Charles de Carteret, his eldest son, inherited his titles and lands.
[6] A monument to his wife Elizabeth Carteret (1663–1717) was in Westminster Abbey until 1847 when having become dilapidated it was removed (all but the inscription) by Lord John Thynne, Sub-Dean of the Abbey and representative of the Carteret family, who re-erected it at his country house of Haynes Park in Bedfordshire.
