ok, so if yours - it is wonderful!
i hoped that they will be YOUR family and i have seen that there some generations back......
at Danubeswabains often some to find in internet as they later searched some. many of them back in german areas of Europe now (after WW2).
for best there to research always with the former german placenames in connection with the lastname at google because most areas were austrian-hungarian and the Danubeswabians spoke german. so when you search a placename best after finding the english Wikipedia to change in the link above from en (english) to de (german). there you will find most time then the german name of place TOO and this is to take for more research at google.
good luck for further research!
