Sir Winston Churchill, FRS (18 April 1620 – 26 March 1688), known as the Cavalier Colonel, was a British soldier, knight, historian, nobelman, and politician. He was the father of John Churchill, 1st Duke of Marlborough, as well as an ancestor of his 20th-century namesake, Prime Minister Sir Winston Churchill.
Churchill was the son of Sir John Churchill of Dorset, a lawyer and politician, and his wife Sarah Winston, daughter of Sir Henry Winston. Churchill was educated at St John's College, Oxford, but he left university without taking a degree.
Churchill was a fervent Royalist throughout his life. He fought and was wounded in the Civil War as a captain in the King's Horse and, after the Royalists were defeated, was forced to pay a recompense fee of £446 (equivalent to around £44,600 in the present day).
After the Restoration, he sat as a Member of Parliament for Weymouth and Melcombe Regis from 1661 to 1679 and for Lyme Regis from 1685 to 1688. He was also a Commissioner of the Irish Court of Claims and Explanations between 1662 and 1668, and a Junior Clerk Comptroller to the Board of Green Cloth from 1664 to 1679.
