Does abt stand for about in the census rolls?

VJ,
I cant thank you enough, I think you hit it on the head, no this is my neighbors family who I got into a discussion with when I bought a thick old book on Italy Illustrated, said the info she came across was all in Italian.
I will run this by her & press her for more details on census, military ...

Looking for Italian ancestors Guissepe Tolassi (husband) & Carmela Vetrone (wife) that came over to America in 1901. They were from Casalduni, Italy.
I was on a page with someone asking about the same name, Vetrone, & lost it, anyone know where to go to search for it? Thank-you. Bob
