The duke was generally considered "horrific"—very ugly, physically deformed, and sexually debauched[1]—yet the privileges of being a duchess compensated for the unfortunate match, e.g. le tabouret: In a letter to her daughter, Madame de Sévigné described an incident that took place at St. Germain during an audience with the Queen.

"[2]Charlotte and Louis Charles had one daughter, Anne Geneviève de Lévis, born in February 1673.

After the birth of her daughter, Madame de Ventadour preferred to reside in Paris separated from her husband, and there were no more children.

A few years after her marriage she secured a new office at court and served as Dame d'honneur to the King's sister-in-law Elizabeth Charlotte, Madame Palatine, between 1684 and 1703.

In 1712, an outbreak of measles struck the French royal family, causing a number of significant deaths.

Deciding that she would not allow the same treatment to be applied to the Duke of Anjou, Madame de Ventadour locked herself up with three nursery maids and refused to allow the doctors near the boy.

Madame de Ventadour continued in her position as royal governess until 1717, when the boy king was deemed old enough to be raised by men.

Between 1727 and 1735, she again served as Royal Governess, now for the children of her former charge Louis XV, whose twin daughters were born in 1727.
