I'm currently researching my family roots in Europe, and I've made it a far back as my great-great-grandfather; Johann Fon of Austria, born in the mid 1800s. All the info I have on him is that my great-grandfather listed his name and place of residence on his Ellis Island manifest.

I have recently found record of a Johann Fon, son of Carolus and Eva Fon, born at St Andrae Bei, Lavanttal, Kaernten (Carinthia), Austria in 1743. Naturally this is not him, but I am interested to research if there is a relation.

Can anyone recommend how to research this further? Thanks, Paul
