This is not the right board for your inquiry as Burgenland and Veszprém county are different areas which, though relatively near to each other, do not intersect. I hope that you also posted on boards for Hungary in general, county Veszprém in particular, and web sites serving the Donauschwaben (Danube Swabians).
Ernest Chrisbacher has published a book with much data on the ethnic Germans from Veszprém, including data on names and origins of the original settlers of the late 17th and 18th century. If you have not heard yet about this book, please visit the web site
http://www.chrisbacher.net/book/I did a cursory check in the book for the family names you listed. Some of the names are indeed mentioned. These names seem to point to the region of Pápa.
Are you certain about the spellings of your names? For instance, "
Keim" might be a misspelling. Could it rather be
Kunn or
Kuhn, or
Kern, or
Klein? Could Früholz be rather Frischholtz? According to the book, a Margarita Frischholtz married in 1760 in Nagytevel. She originated from the "Oberpfalz" (
Upper Palatinate) in Germany. Some of the Kunn/Kuhn originally hailed from Grossreinfeld in Germany. The book also lists a Barbara Sabaditsch, apparently hailing from
Pama in today's Burgenland. She married 1746 in Nagytevel.
