I solved the mystery with the help of my grandmother. She finally remembered something! Annunziata changed her name to Mary, just like her sister did, and they actually lived right across the street from her sister, who was my great-great grandmother. Their names are only 2 families away from each other in the 1940 census. So happy to have made this discovery!
Looking for- Bove, Santacroce, Vigliotti, Greco, Pascarella, Suppa, Carfora from Cervino, Caserta and surrounding area.
