hi there!
my name is Vito Milana and I also live in Melbourne. I am 99% certain that we are related on your great-grandfather's side - Andrea Guccione (born Vizzini 6.9.1889) who married Giovanna Monte. I know of 2 children: Antonio (born 1918) and Lucia (born 1920). Alot of these people lived in NY though.
I've done quite some research on my family and would love to swap some information.
my email is :
vitomilana@hotmail.complease drop me an email and we can take it from there if you like.
Vito
