Hi Marie,
There are a few Violantes in the death index who died in Pennsylvania. Go to http://www.allonesearch.com/ and check off "People", then use the death index search engine. Ironically, my granfather, Emilio, copied a few things from your grandfather. He was reputed to have married a woman in Ansonia, CT after his young wife died. Then he supposedly left her for another woman in Ansonia, married or not, then left her and returned to Abruzzo, whwre we know he was with yet another woman who I later met when we went to Abruzzo. He ditched her and took up with another woman. Don't know how many cousins or other relatives from that relationship. Francesco doesn't ring a bell, though. Violante is about as common as Johnson, so it will be a tough search. Emilio was from Celano, Abruzzo, as was his brother Gabriel. I'll be publishing my tree on Famity Tree.com soon, so stay tuned.
