Consuelo Vanderbilt

Consuelo Vanderbilt-Balsan (formerly Consuelo Spencer-Churchill, Duchess of Marlborough; born Consuelo Vanderbilt; March 2, 1877 – December 6, 1964) was a socialite and a member of the American Vanderbilt family. Her first marriage to the 9th Duke of Marlborough has become a well-known example of the advantageous, but loveless, marriages common during the Gilded Age. The Duke obtained a large dowry by the marriage, and reportedly told her just after the marriage that he married her in order to "save Blenheim Palace", his ancestral home.

Although the teenage Consuelo was opposed to the marriage arranged by her mother, she became a popular and influential Duchess. For much of their 25-year marriage, the Marlboroughs lived separately; after an official separation in 1906, the couple was divorced in 1921, followed by an annulment. Her first marriage produced two sons, John Spencer-Churchill, the 10th duke, and Lord Ivor Spencer-Churchill. She went on to marry the wealthy French aviator Jacques Balsan and continued her charitable endeavours. She lived in France before World War II, when she and Balsan returned to live in New York and Florida. When she died, she was buried near her son, Lord Ivor, not far from Blenheim Palace.
