My grandmother’s maiden name was Caterina Zando. She was born in Falcade in 1882. Her father was Sebastiano Zando and her mother was Maria Elisabetta Ganz. Her father,Pietr'Antonio Ganz and mother Domenica Depellegrini.
You also mentioned in your e-mail the name Scola. My grandfather, Robert Martin Zando was born in Innsbruck Austria in 1879. His father was Sixtus Zando, but his mother was Veronica Schota. This could be a spelling error or it could be the same last name.
