whre you able to find their marriae record in NYC?
I checked the database on the Italiangen.org website and found a possible record:
Barbella Giuseppina Aug 14 1904 Kings 6189
Amaro Ginno B Aug 14 1904 Kings 6189
I know names are off but maybe this record worth to be investigated better...
Most likely they were married in Brooklyn not in Italy being the bride born in the U.S.
