Louise Marie Madeleine Fontaine
Louise-Marie-Madeleine Guillaume de Fontaine (after marriage known as Madame Dupin; 28 October 1706 – 20 November 1799) was a French "saloniste".
Marie Émilie de Joly de Choin
Louis, "le Grand dauphin" fell in love with her after the death of his consort in 1690 and began a liaison with her. Simultaneously, she was in a relationship with Count Francois-Alphonse de Clermont-Chaste, a member of the entourage of the maréchal de Luxembourg. Luxembourg advised Clermont-Chaste to marry Choin in order to acquire power over the crown prince through her. It was rumoured that Marie Émilie and Clerment-Chaste planned to dominate the throne by producing a child with her, which they would present as the child of Louis. When these plans were discovered, after the correspondence between Marie Émilie and Clerment was presented to the king, they were both exiled from court, which did not, however, permanently end her relationship with Louis.
