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".
Philippe II, Duke of Orléans
In November 1721, at the age of twelve, Louise Élisabeth d'Orléans was married by proxy in Paris, Louise Élisabeth and her younger sister left for Madrid. Despite a cold reception from the Spanish royal family, especially by Elisabeth of Parma, the stepmother of her husband, she married Louis of Spain on 20 January 1722 at Lerma. Her dowry was of 4 million livres. The last of this triple alliance was Philippine Élisabeth who never married Charles; the marriage, though never officially carried out was annulled; the French sent back Mariana Victoria and in retaliation, Louise Élisabeth and Philippine Élisabeth were sent back to France. Franco-Spanish relations only recovered in 1743 when Louis XV's son Louis de France married Mariana Victoria's sister Infanta Maria Teresa Rafaela of Spain.
