Hi, I`m Hans Sperandio from Vienna.
My father was born in Feldkirch, Vorarlberg,
but all his ancestors were coming from Imer,
Trentino. They immigrated to Austria approx.
1880. My aunt Theresia Sperandio died there
ca 15 years ago. Other names in the family
tree were Doff-Sotta, Bettega and Gobber.
Maybe this might help you,
