Educating Sophie - the Aristocratic secular nun

When Sophie de Grouchy was young, no tutor was assigned to her. But she benefitted from her mother's instruction, a woman known for her intellect, culture and generosity. And she was allowed to participate in her younger brothers' lessons. She did so well at this that when their tutor was sick, she took over their Greek and Latin instruction.
 
At the age of 18, she was sent to a finishing school in Normandy, at Neuville-les-Dames, near Macon, a secular convent for ladies. She received the title of Chanoinesse, and was addressed as Madame. 

In order to gain admission, one had to pay a substantial fee and maintenance amounting to 9000 pounds per year, but also provide proof of lineage: 9 generations on the father's side and 3 on the mother's.
The convent was not ostentatiously religious. Pupils studied Latin and modern languages, and worked on their accomplishments. They hosted parties, the purpose of which was to find husbands of the right sort.

​In an environment that was religious and socially privileged, she became an atheist and socially aware. She discovered Voltaire and Rousseau, she read and translated Tasso's Jerusalem, and an unnamed work by Young (probably his Tour of Ireland). Her aunt, visiting her, worried about her health - her eyes were puffy every night and ached so that she feared it might be a form of gout. And yet Sophie kept on with her work.
 
The building Sophie lived in is long gone. But Neuville now has an Allee Sophie de Grouchy, on which stands an elementary school, l'école Condorcet. There are many schools named after Condorcet in France, but if this one is named after the Marquise, not the Marquis, then it is, as far as I know, unique.
