Personal life

On August 15, 1907, Moore married the then Duke of Poli and Guadagnolo Don Marino Torlonia (1861–1933) at Old Orchard, her parents' estate in Belle Haven, Greenwich, Connecticut. She was nicknamed, "the Dollar Duchess" by the media. Upon his brother Augusto Torlonia's death in 1926, her husband became the 4th Prince of Civitella-Cesi. Together, the Prince and Princess of Civitella-Cesi had four children: In 1922, the Duke of Torlonia fought a duel with Count Filippo Lovatelli, the famous Italian sculptor, over a statue of the Duchess, causing an international sensation. The Prince of Torlonia was having an affair. In 1925, the couple separated and in 1926, the Duchess filed for divorce in the United States. Her American citizenship was brought into question, but the Connecticut courts decided that her residence in the state was legal and granted her divorce in February 1928. Once settled in the United States she became a socialite, active in society life in New York City and Newport, Rhode Island. Moore died at her home, 375 Park Avenue in New York City, on December 21, 1941.
