Where is my brother's first daughter (my niece)? When her mother and my brother got divorced, they severed all ties and we haven't seen her in over 40 years. All I have is her mother's maiden name, and I do know that the mother remarried and niece was adopted by the new husband. No one in my family had the guts to ask my brother where she was, even if we couldn't understand not knowing where your child was for her entire life, and now he's gone. We'll never know.
What do the mystery keys in my junk drawer go to? I'm afraid to throw them out, as sure shooting I'll find some locked box that can only be opened with the key

Who are the people in my grandmother's photo album? We found a photo album of some people in our family, but others are mysteries. There were some pictures of George Washington and Abraham Lincoln, so we think they just might be "fake" people in there, the way some photo albums sold today come with a picture in them.
When I converted to Judaism, I was surprised to find the service very familiar (I was raised Protestant, with no Jewish relatives and few Jewish friends). The music, the prayers were all familiar and I "knew" what was going to happen next. I do have some memories of my mother buying matzoes in the spring, and fuzzy memories of going to a synagogue. She was supposed to be Episcopalian. Much later I found that my mother's family name was changed from a more Jewish sounding name, and I suspect that her family was at least part Jewish and immigrated to escape persecution (which did happen in their city in Germany). Both my parents are gone, and I never wanted to uncover what was apparently a secret, anyway.
