Thanks for your reply. My ancestor is Lajos HART, born in about 1895 in Tiszanagyfalu. He was in the military in WWI and reportedly was captured and then released at the end of the war, to make his own way back home. I was looking for a military record to get more information about him.
If I used the kramerius link correctly, I did not find any listing for Lajos Hart.
Thank you for any help or ideas on where to look for information.
