I am trying to research my maternal line, Mletzko who came from Helmstedt in Germany. My grandfathers name was Wilhelm Joseph, great grandfather was Joseph. I have two sisters to my grandfather - Anna became Piosek at marriage) and Magda who married a Paul Grezciak (Graczyk?). They adopted a boy by the name of Hubert. I presume he took the family name. According to my aunt Hubert is (or was) on the Internet. We don't know if he is still alive. Again we presume he had children. He or they may or not be in Germany or anywhere else in the world. If anyone recognises any of these names or knows of anyone who does I would be very grateful.
