I’m looking for information on Nathan Chess. Last known address was in N.Y. or N.J.He was married to Freida Chess. Nathan was Jewish and came to the U.S. from Russia. Freida, my grandmother was also Jewish and came from Austria before WWI.Their children were Leo Chess and Eva Chess. Nathan and Freida separated either before or during WWII. His children lost contact with him and the family would like to find out what happened to him or where he is buried.
