I am searching for ancestry to prove Jewish decent as my family is under the impression that we are already Jewish. My grandmother's (June Claire Romp) mother's (Clara Verschoote) name was Maidgham Vandenbush and they lived in Belgium. I have no other information and would like to know where I can find if they were Jewish or not? I am also seeking information on what exactly I must know before
I can convert if I cannot prove legacy. Please direct me?
