He was the third son of Charles II by his mistress Barbara Villiers (later Duchess of Cleveland) and was known first as George Palmer, as she was married at this time to Roger Palmer, Earl of Castlemaine. Born at Oxford on 28th December 1665 he was created Baron of Pontefract, Viscount Falmouth and Earl of Northumberland in 1674. In 1683 he was created Duke of Northumberland.

His first wife Catherine was daughter of Robert Wheatley and her first husband was Thomas Lucy. She was buried on 3rd June 1714. Her sister Anne married Lord George Douglas and sister Elizabeth married a brother of the Duke of Berwick. All were at some time in the Convent at Hammersmith. George's second wife (not mentioned on the stone) was Mary, daughter of Henry Dutton and sister of Captain Mark Dutton. She died at Frogmore, Windsor and was buried in the vault on 11th September 1738. He had no legitimate children so his line became extinct at his death.

His brother Charles Fitz Roy, Duke of Cleveland is also buried in the Abbey.
