They are all from Lieser, Rhineland, Germany along the beautiful Mosel River. http://en.wikipedia.org/wiki/Lieser_%28Mosel%29
I also found many others as well. It is a WONDERFUL feeling!! HAPPY, HAPPY DAY!
Update: I actually found four more sets making it a total of 18 direct great grandparents. This has been humbling, gratifying, and overwhelming. It brings tears to my eyes. It's hard to put into words how joyful this feels. I am happy for my ancestors and happy for me. Someday I will meet them. That alone is an overwhelming feeling. I can now trace one line back to the mid-1500's to my 12th great grandparents. :)
