I am researching a John Biro. His WWII draft card says he was born on 25 Dec 1887 in Kisvarda, Hungary which I understand to be a small town in Szabolcs-Szatmár-Bereg.

We believe that his family was Catholic (but there is a small possibility they could have been Jewish).

I am wondering if anyone knows of any resources to find his actual birth record or possibly immigration records. Searches of Ancestry.com so far have not led to anything conclusive - but still checking.

Thanks in advance for any help you might be able to provide.

Regards,
Ken
