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".
Duchess Helene of Mecklenburg-Schwerin
On 30 May 1837 Helene Luise married Ferdinand Philippe d'Orléans at the Palace of Fontainebleau. The Archbishop of Paris, Hyacinthe-Louis de Quélen had used the pretext of religious differences to forbid it taking place in Notre Dame de Paris. She was chosen as the bride for the Duke to form of alliance with her cousin Frederick William III of Prussia, despite the fact that she was a Protestant, and that she was considered to be a liberal, and not considered a beauty: described as an ambitious person, she accepted the proposal against the will of her family because she wanted to become a queen.
