"Styled Mademoiselle d'Armagnac, she was a celebrated beauty at the court and was a favourite of Louis XIV and was described by Madame de Sévigné as a beautiful and likeable woman. After the marriage of her sister Marie to the Duke of Valentinois (future Prince of Monaco) the court paid close attention to the range of suitors that were offered to Charlotte. These included the famous Saint Simon; the Margrave of Ansbach, brother of the future Queen Caroline of Great Britain as well as various other French noblemen. Another candidate was Louis Alexandre de Bourbon, Count de Toulouse, youngest son of Louis XIV and his mistress Madame de Montespan.
