If you have family from what was Hungary pre-WWI, Czechoslovakia
between the wars, and is now Zakarpattya Oblast, Ukraine, the 1921

great-great grandparents! Here are instructions about how to navigate
the site:

If someone wants to work with me to create a transcription project to
index the Jewish records out of here, please contact me off-list.
