Consuelo Vanderbilt-Balsan (formerly Consuelo Spencer-Churchill, Duchess of Marlborough; born Consuelo Vanderbilt; 2 March 1877 – 6 December 1964) was an American socialite and member of the 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 through the marriage and reportedly told her just after the wedding that he married her in order to "save Blenheim Palace", his ancestral home. Wikipedia
