Carteret was left an orphan at the age of five, and was brought up by his grandmother Elizabeth de Carteret, a daughter of Philippe de Carteret II, 3rd Seigneur de Sark, whom Samuel Pepys called "the most kind lady in the world".

[1] In 1681, when Carteret was fourteen, King Charles II created him Baron Carteret, of Hawnes, in recognition of his late grandfather's outstanding loyalty to the House of Stuart, both during the English Civil Wars and after the Restoration.

Carteret married Lady Grace Granville, a daughter of John Granville, 1st Earl of Bath, and by her was the father of John Carteret, 2nd Earl Granville and 2nd Baron Carteret.

Carteret died in 1695, aged only 26; his widow outlived him by half a century and in 1715 was created Countess Granville.
