I have been researching the Zeok side of the line. Mary was my great grandmother and I have gotten as far as her parents name and place of birth. I have been to Pittsburg once to do research but did not find much. We saw Albert's grave but never knew he was John's son. Do you have any pictures of Mary? She died before my mother was born and my grandfather died when she was 3 and we don't have any photos of any of the Zeok/Haver relatives. I would love to see what she looked like. Thank you for replying. Good luck with your research and I am sorry I wasn't more help.
