Okay, I'm going to throw this out and see what kind of response I get. Here's my situation. My wife was raised a Christian. When we were married, as far as she and I were concerned, she was a Christian. A few years later she found out from her mother that her grandmother was Jewish and never said anything to anyone until she was on her deathbed. So, in essence, my wife's mother married a Christian man and had 8 kids, which were raised as Christians, because she also did not know about her mother's heritage.
My understanding, based on what I know about Jewish lineage, is that since my wife's grandmother on her mother's side is Jewish, my wife is Jewish. What do I do?
