Hi Rob.
Mt Grandfather was Antonio Gianoli, he was born in Teglio, Sondrio Italy in 1855. His father was Gervasio Gianoli & his mother was Catherina Bruni. Antonio immigrated to Australia in 1881. I don't know if he is related to Maria Teresa Gianoli, could have been a brother or cousin??
The information I have regarding Antonio Gianoli I obtained from his children's birth certs. & his marriage cert.
Interestingly there is a road (via) in Teglio (Google maps) named Via San Gervasio and it becomes Via Gianoli. Teglio is a grape growing district & my grand father had a little vineyard in Aust. Maybe the Gianoli's were connected with vineyards in Teglio??? Might be a starting point for researching Gianoli's in Sondrio.
