Charles Spencer, 3rd Duke of Marlborough
The third Duke lived at Blenheim from time to time but preferred to live at his house in Langley, Buckinghamshire. He had a daughter called Lady Diana Spencer who was engaged to the Prince of Wales, although the marriage never took place. Also like the recent Lady Diana Spencer who married the Prince Charles, the 3rd Duke’s daughter died young.
He led the British expeditionary force on Continental Europe in the early part of the Seven Years' War, but died in 1758 , the only one of the Dukes of Marlborough to die on campaign.
