Reading "Il Patriziato Subalpino" by baron Manno, one knows that princess Felicita (also called Madama Felicita) had her own court: first squires (primi scudieri), second squires (secondi scudieri), first lady-in-waiting (prima dama), aide-de-chambre (aiutante di camera).. However the years reported there are all after the death of her sister Eleonora, maybe while Eleonora was alive they shared the same court?
In the Turin Royal Palace there is now an apartement that is called of Madama Felicita, so I supposed she lived there.
Finally I found out that in 1786 she founded the "Convitto per vedove nobili e di civile condizione" (boarding for widows of noble and civil condition).
The new building she had build for that looks quite impressive and is on the Turin's hill, quite near to the Villa della Regina royal palace. Expenses for the building and the maintenance of the Convitto were largerly paid by her and by her brother.
I'm not really sure why they considered this charity, maybe because widows were considered weak people to protect from the world or maybe because the widows that were there were poor and could have a dignified life elsewhere..
Father Giovanni Battista Canaveri, confessor of the princess and probably inspirer of this work, was called to be the director. He later became bishop of some Piedmontese diocesis.
The princess had there an apartment for herself composed of an audience room, 3 rooms and 3 more little rooms one of which was a personal chapel.
She also managed to have St Felicita's relics transferred to the main chapel of the Convitto from somewhere else in Turin.
Before flewing to Rome she gave her forniture to the Convitto in an attempt of preserving it from French confiscation.
I had all this information form the site of the Convitto that nowadays is an house for elderly people.
