I have a letter my uncle gave me back in 1996. It was from our cousin living in Riga, Latvia. The letter is postmarked 1973. The cousin's name was Israel Fiselsons (Fiselsohn). He said he was a wounded war veteran that survived WWII by being in the Army while most of his family perished. He was living in his mother's apartment with his wife (a dentist) and 10 year old daughter, Ilana. No name for the wife.
I was able to determine his mother's name (finally) as being Hinda (Shirren) Fiselsohn so was able to place him as a cousin to our Weitzman family but have been unable to learn the name of his wife or whatever happened to his daughter. I've tried all the resources I know about without success. Ancestry, Family Finder, Jews of Latvia Surnames etc.
Any suggestions would be greatly appreciated.
