I don't know if I have any connections. My mother is German and came from Hannover, Germany. Her mothers maiden name was Kahlmeyer (several different ways to spell it so it seems) and they originated from the Eichfeld area which we think is near the eastern border. I have several names in the Kahlmeyer line, unfortunately all from one family. I also have the name of Hupe, the married name of one the sisters. Also a Kaczmayrek? maybe ends with ech. I have found a site that lists names within several variations of the name we are both searching. There is also the facility to download Gedcom files, although I haven't had much success getting them opened. I can't remeber the name of the site at this moment but will let you know as soon as I find it. If you know how to use Gedcom files or have any luck, please let me know, as I am trying to trace several names within my whole family.
