Note A — CX. To Madame the Duchess de Montmorency (née des Ursins).[A]
London Visitation Nuns (Harrow translation
When becoming a postulant at the Visitation, the Duchess de Montmorency wished not only to renounce her titles of nobility, but also to change her baptismal name of Marie-Félice, a custom which was not usual at that time. She was named Marie after Marie de Medicis, and Félice after her maternal uncle Félix Peretti (Pope Sixtus the Fifth). At her clothing she dropped these names and was from henceforth only known as Sister M. Henriette. She became Superior at Moulins some years after the death of St. Jane Frances.
