I don't know excatly where you are going with this, but I thought that I would put my two cents in.
My best friend is Mulism and a SK. We treat her just like any other member. She teaches us new things about her faith which are somewhat like ours, but with a better twist.
But if you are considering of searching your Jewish roots I encourage that you do it, cause maybe if you don't do it now you may never do it.
I hope that I anwsered your question. If not, I'm sorry
