The Surname I'm going to mention today is one of my Italian names, Bionaz
My mom Elizabeth Joan Bionaz Baker - born in San Francisco California - 1931
My grandfather John Camil Bionaz - born in Southfork, Cambria County, Pennsylvania - 1904
My great-grandfather John Elere Bionaz - born in Gignod, Aosta, Italy - 1867
My 2great-grandfather (possibly) Peter Bionaz - somewhere in Aosta, Italy - about 1840
I'm not sure about the information on Peter.
Now there is a second Bionaz line that ties into my line, but as far as we know they are not connected.
John Elere Bionaz married Orpheline Boche and Orpheline's sister, Amelia, married a John F. Bionaz. However the two Johns have different mother's names and were not aware of being related.
