Winston Leonard Spencer Churchill was born November 30, 1874 at Blenheim Palace, home of his grandfather the 7th Duke of Marborough. His birth was unexpected; his mother went into labor after "a rather imprudent & rough drive in a pony carriage." Despite the circumstances of his premature birth, the infant Churchill was "wonderfully pretty" with "dark eyes and hair & v[er]y healthy."
