Hi Mr. James Maiorana
We're from Long Island too.
Sorry to hear your at a cross road.
Did your grandfathers siblings come to America?
I would think there would be information at Ellis Island.
I'm not sure - but would think they have records of people who had entered America available to the public.
If you have any information on your grandpa
then start with that at Ellis.
Wish you luck
let me know how you made out.
