Jessica,
I am researching Providenzia Vacanti, who lived in Omaha and came across this post. The names that you mentioned don't match what little I have, but I was hoping you might be able to shed some light for me.
The only thing I know for sure is that Providenzia Vacanti b. 29 Apr 1887 in Italy, d. 16 Jun 1964, married Santo Bonacorrso and lived in Omaha. I have her parents as Alfio Vacanti and Lucia Circo. Most of the parental information is based on a birth certificate for John Alfio Vacanti who married Grace Puglisi. I believe that John is Providenzia's brother, but I haven't been able to confirm that.
If any of this rings a bell, please let me know.
Al
