    I believe Jonah Blechman is 50% Ashkenazi Jewish and 50% German non-Jewish. From what I have researched I believe he is the son of Bruce J. Blechman and Sylvia M. Lang. If that is the case Jonah is Russian Jewish and Lithuanian Jewish on his fathers side and German/possibly other on his mothers side. I know for a fact that his mothers maiden name was Lang and to add to the certainty I found this after the ancestry research of Jonah’s potential parents…
