Sir Winston Leonard Spencer Churchill is my 12 cousin 1x removed. The ancestor that we share that connects us is Ann Tanfield (1516-1548), my 10th great grandmother.

When Winston Leonard Spencer Churchill was born on November 30, 1874, his father, Lord, was 25 and his mother, Jeanette, was 20. He married Baroness Clementine Ogilvy Hozier on September 12, 1908. They had five children in 13 years. He died on January 24, 1965, at the age of 90, and was buried in Bladon, Oxfordshire, England.

Born into the aristocratic family of the Dukes of Marlborough, a branch of the Spencer family, Winston Leonard Spencer-Churchill, like his father, used the surname Churchill in public life. His ancestor George Spencer had changed his surname to Spencer-Churchill in 1817 when he became Duke of Marlborough, to highlight his descent from John Churchill, 1st Duke of Marlborough. Winston’s father, Lord Randolph Churchill, the third son of John Spencer-Churchill, 7th Duke of Marlborough, was a politician; and his mother, Lady Randolph Churchill (née Jennie Jerome) was the daughter of American millionaire Leonard Jerome. Winston was born on 30 November 1874, two months prematurely, in a bedroom in Blenheim Palace, Woodstock, Oxfordshire.
