Hello, my name is Christian Ehmig. The name of my father is Peter Ehmig. We both live in Germany. I don't know much about my grandfather, but he also lived in Germany, so there could be some relation because the dates of your grand grand grandfather fit to the time my grand grand grand could have been living... Also his name is Peter Ehmig, so my grand father could have given my father the name Peter Ehmig because of that... But I don't know if I'm right about that... Perhaps you know something more and can send me an email, because RENÈ EHMIG contacted me a few days ago, he lives in France and knows about an Ehmig who was born 1783 in France. He is also sure that the Ehmigs come from a Germanic Tribe, this would be very interesting, so if you know some more, please contact me!
