So... Let me get this straight... His Father's Mother was Jewish? But his Mother is Irish-Catholic or whatever, who cares... BUT like you said "We do!" BUT I don't think that this makes him Barley a Jew. I guess he's more like NOT A JEW. Because he doesn't have a Jewish Mother like we do, right Yakov and Zev? Catholics huh? Oy Vey! - From Musical Jew. Shalom.
If you have Jewish blood, we mark you as "Barely a Jew". Make of it as you will.
