9TH DUKE OF MARLBOROUGH

This is Winston Churchill's cousin. He was nicknamed 'Sunny' but not because he had a sunny nature. He had an unhappy childhood and this had made him a melancholy and sad man. (He was actually called Sunny because when he was young his 'title' was the Earl of Sunderland.)

But Sunny loved Blenheim very much and made many changes to improve it such as building the beautiful water terraces and restocking the library with 10,000 leather-bound books.
