Sir Charles Turner, 1st Baronet (1666 – 24 November 1738) of Warham, Norfolk was an English lawyer and Whig politician who sat in the English and British House of Commons for 43 years from 1695 to 1738. He was a brother-in-law of Sir Robert Walpole, and held public office almost continuously from 1707. By 1730 he was the longest-serving MP in the House of Commons.
Turner was baptised on 11 June 1666, the son of William Turner, attorney-at-law of North Elmham, Norfolk, and his wife Anne Spooner, daughter of John Spooner.[2] He was educated at Scarning and Norwich and was admitted at Caius College, Cambridge on 29 April 1681.[3] He was also admitted to the Middle Temple on 22 July 1684 and became a country attorney like his father. His fortunes were boosted by the improving success of his own family and his influential connections, which were to include the Walpole family. In April 1689, he married Mary Walpole, daughter of Robert Walpole and sister of Sir Robert Walpole the first Prime Minister.[4]
Turner's first wife Mary died in 1701 and by 1705 he married, secondly, Mary Catelyn, widow of Sir Nevil Catelyn of Kirby Cane and daughter of Sir William Blois of Grundisburgh, Suffolk. He died suddenly on 24 November 1738, at Houghton and was buried at Warham. By his first wife he had a son who predeceased him and four daughters.[4] He was succeeded by his younger brother John.[6][7]
