Really? You’re kidding me. But I do believe that with all the pogroms against Ashkenazie Jews , there is a theory that their fathers are Ukrainians, hence Uman.
1. There is no such “theory”. Unfounded speculation by random nutcases does not constitute a theory.
2. What the *$#$% does Uman have to do with it?
3. Even if it were true, so what? How could it be even remotely relevant?
