She was one of those people who are fortunate enough to spend their lives in the service of kings without knowing anything of what is passing at Court.

She was a great devotee; the Abbe Grisel, an ex-Jesuit, was her director.

Being rich from her savings and an income of 50,000 livres, she kept a very good table; in her apartment, at the Grand Commun, the most distinguished persons who still adhered to the Order of Jesuits often assembled.

The Duc de La Vauguyon was intimate with her; their chairs at the Eglise des Reollets were placed near each other; at high mass and at vespers they sang the "Gloria in Excelsis" and the "Magnificat" together; and the pious virgin, seeing in him only one of God's elect, little imagined him to be the declared enemy of a Princess whom she served and revered.

On the day of his death she ran in tears to relate to the Queen the piety, humility, and repentance of the last moments of the Duc de La Vauguyon.
