Anna Eleanore Sullivan, previously Eleanora Franchi (12 June 1750 in Lucca - 14 September 1833) was an Italian courtesan, mostly known in history for her relationship with Axel von Fersen, the alleged lover of the French queen Marie Antoinette. She participated in the famous Flight to Varennes, the attempt of the French royal family to leave France during the French revolution, with the assistance of Fersen.
Eleanora Franchi was the daughter of a tailor in the Republic of Lucca. She was active as a ballet dancer and at the age of fifteen married a dancer in a travelling theater company, Martini, but was widowed soon after. At the Carnival in Venice, she met Charles Eugene, Duke of Württemberg, and became his mistress. With him she had two children: Eugen Franchi, born on 5 October 1768, and Eleonore Franchi, born on 17 January 1771, who was created Freiin von Franquemont. Active as a courtesan, Eleanore was at one point a lover of Joseph II, Holy Roman Emperor, but was exiled by his mother, Maria Theresa of Austria. In Paris she married an Irish officer named Sullivan and followed him to India. Once there, she met Quintin Craufurd and became his mistress before returning to Europe with him.
