my family comes from a long line of german jews. My grandma was born in 1930 and survived a concentration camp along with her sister and father. I am interested in converting but i have no idea how to start.
Is your mom or dad Jewish? If your mom is fully Jewish, meaning her mother was Jewish, her mother's mother was Jewish, and so on, then you are already Jewish by Jewish law. It should be very easy for you to get a conversion, although I don't know if that's necessary if your mother is Jewish.
