Looking or information on John (Johann) Fon & Maria Wolf (spouse). I have American records for John Fon but looking for more on Austrain / Slov. heritage.
John Fon SR. DOB (approx) 4-4-1880
Maria Wolf (Fon) DOB approx 1880
I have records that name Predgrad as place they came from. There is also a Dalben Austria listed on John Fon Sr. place of birth on a WWII Draft card. Passports indicate Predgrad Yugoslavia and something that looks like Staritrg Yugoslavia. There are also letters to John Fon Jr. from a sister(?)(Maria) in Staritrg.
They had a son in the USA named John Fon DOB 4-3-1908 and on the birth certificate it states ages of parents as both 28. And Austria as place of birth.
How do I go about obtaining correct information on these people when there are so many different places to look and I don't speak the language? There is a rumor that Fon was changed at one point and time also.
Any help would be greatly appreciated, thank you.
