Because they were poor, her parents appealed to the future wife of Louis XIV, the marquise de Maintenon to help with her education.

Madame de Maintenon arranged the marriage of Françoise Charlotte with a member of the powerful House of Noailles.

Thus, from very humble beginnings, Françoise Charlotte rose to the upper levels of French society.

Her nephew by marriage was Louis Jean Marie de Bourbon, Duke of Penthièvre, one of the wealthiest man in Europe.

Others included the Duke of Éstrées, great-nephew of Gabrielle d'Estrées, a mistress of King Henri IV.
