My grandmother Dorothy may have never known that she was one of eight children. Her mother died when she was four. Soon afterwards, Dorothy and her youngest brother, the only sibling she ever mentioned, went to live with an aunt. We do not know what happened to any of the other children. We do not even know the name of the aunt.
