Henry Hyde, 2nd Earl of Clarendon

Henry Hyde, 2nd Earl of Clarendon, PC (2 June 1638 – 31 October 1709) was an English aristocrat and politician. He held high office at the beginning of the reign of his brother-in-law, King James II.

He was the eldest son of Edward Hyde, 1st Earl of Clarendon and his second wife, Frances Aylesbury. He was thus a brother of Anne Hyde, and maternal uncle to both Queen Mary II and Queen Anne. Both he and his brother Laurence Hyde were brought up partly at Antwerp and Breda, by their mother. Clarendon before 1660 made use of Henry as copyist, decipherer, and confidential secretary, in his correspondence with distant royalists.

Soon after the return of his family to England in 1660 Hyde married Theodosia, daughter of Arthur Capell, 1st Baron Capell of Hadham, and sister of Mary Somerset, Duchess of Beaufort. She died in 1662, and in 1670 he married Flower, widow of William Bishop and Sir William Backhouse (kinsman of her father), and daughter of William Backhouse, gaining the manor and house of Swallowfield Park, Berkshire; later she was First Lady of the Bedchamber to Queen Anne. Anne later took a dislike to her aunt, no doubt influenced by her best friend Sarah Churchill; Sarah detested Flower, whom she called "the madwoman". He had the courtesy title Lord Cornbury from 1661. He was Member of Parliament for Wiltshire, until 1674.
