I am a Haslacker also.I have just started my search on the family tree. I have been told that the Haslacker name was orginially Van Hausenlacker....Not the correct spelling. I have not found anything yet to that sound. If anyone has any information on Haslacker, Lantz or Nazelrod family surnames, feel free to email me. I would be happy to send the the information i have in return for what u may have. Thank you.
