Dear Giovanna, I´m sorry but I know my ancestrors only to my
grand-grandfather (Angelo Pavan), and I don´t know any "Vittorio" or "Santo" in my genealogy... but all of them are from Treviso!, then surely may be a link some generation backward.
Yo can see the little info I have, at
http://www.nestorpavan.com There may be some names you know, actual Treviso residents.
Sorry my broken english...
Ciao,
Néstor Pavan
