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".
Charlotte Aglaé d'Orléans
Upon the death of Duchess of Châteauroux, her influence dwindled for a time. In 1744, however, she was able to secure for her daughter, Princess Maria Teresa of Modena, a marriage to the Duke of Penthièvre, the richest noble in France. Louis Jean Marie de Bourbon, was Charlotte Aglaé's younger first cousin and was the heir to the vastly wealthy "House of Bourbon-Penthièvre". The couple married happily in 1744 and had two surviving children. Their eldest child, the Prince de Lamballe, married Maria Teresa Luigia di Savoia, the future friend of Marie Antoinette, in 1767. Their second child, Louise Marie Adélaïde de Bourbon, married the Duke of Chartres, (known as Philippe Égalité during the French Revolution of 1789) and later became the mother of Louis-Philippe I, King of the French.
