Hi Debbie,
The only WOLKERSDORFER I found in my family tree so far is Maria WOLKERSDORFER, who had a son Georg. His last name, however, is after his father, KERSCHBAUM.
You can see that here:
http://wc.rootsweb.com/cgi-bin/igm.cgi?op=GET&db=_diana_...I haven't been able to search further down yet. As the children were usually named after an ancestor, it's very likely that I will find a Georg WOLKERSDORFER someway down the line. Right now, I don't have the time to do it, and as that part of my family is from Hungary, I also don't know how to do it, as I don't speak the language.
Hope you find the Georg you are looking for.
Diana
