Apologies for the delay.Family info is that Rosetta had two brothers and '2 1/2' sisters - her father remarried after first wife died.As far as I know Rosetta was also from Abruzzo.
I found a map online that has a Via Gentile and Via Bucci in the same neighbourhood in the frazione of San Nicolò a Tordino in the province of Teramo in Abruzzo, but I have not found out yet if that was definitely where they came from.You can see this area if you search on 'via bucci, abruzzo, italia' on google maps.
Rosetta married Antonio Bucci in 1907 and they came to America between 1908-1912.
I think there were some Gentiles who were victims of mine accidents in the area of Pennsylvania where Toto worked.I have seen accident records online.
Another male name in the family is Guerino, but I'm not sure whether that came from the Gentile side.My grandmother had two brothers but they both died young.
All best with your search, and I'd be interested to hear any additional details you might have that match up with the above.
