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 Anne de Bourbon (1697–1741)
Marie Anne secretly married her lover, the Duke of Joyeuse, in 1719. Her husband, Louis de Melun, was the son of the Prince of Epinoy and a princess from Lorraine. Louis was also a great great grandson of Gabrielle d'Estrées. He was married to Armande de La Tour d'Auvergne, a daughter of the Duke of Bouillon and grand daughter of Marie Anne Mancini (she died in 1717). In 1724, during a hunting party at Marie Anne's ancestral home, the Château de Chantilly, Louis disappeared and his body was never found. Naturally distraught, Marie Anne never married again. She was never to have any children.
