Hungary-Austria

Given all the turmoil of that region through the 20th century, the only likely bet would be sacramental records (baptism, marriage, etc) of the local churches and not through any government.

Of interest only to me, one of my German speaking great-grandmothers was born in Hungary in 1874 (by the Neusiedler See). After World War I, the area became part of the Burgenland state in modern Austria. In US census records she is correctly identified as being “Hungarian” even though she didn’t speak it. A bunch of people from the same area emigrated to the Stevens Point area of Wisconsin where they became known as “Bohemians”, even though Bohemia was an entirely different part of the empire.

Go to the website of the Mormon Church’s Family History Library, and look up the name of the town in their library catalog. Chances are they will have some genealogical materials — often church records — available on microfilm that can be rented at your local LDS Family History Center for a small fee. (Caveat: The records will usually be in the local language, or Latin.)

You might want to poke around here; there is a ton of information, and much of it is of use to people doing non-Jewish genealogy as well.

Thanks for that link. Following it, I find they hold Catholic church microfilm records for his village up to 1906. So that would cover his parents and grandparents. As I live in the UK how do I do not know if there are such things as LDS Family History Centres. So how can I get my hands on them?

Edit,

I find there is an LDS 20 miles from here . So thanks again for that information.
