Tammy; The name Ketter actually goes back to the Romans.Too long for this forum. There were three brothers from the Moselle River area (Luxembourg - Germany and France constantly claimed ownership). They immigrated to Wisconsin, or that area, and spread out from there. Have you any further names of grandparents, gr grandparents, etc.? I believe two of the brothers were Peter and Walter. One of Walter's descendents was Mathias, my gr.grandfather.
