Is this Raymond Dieter, Orval's son? Well, anyway, I have information from the Evangelical Lutheran Church in Arheilgen that has Johannes, and the two prior generations. I have Johannes, born 1630, Jacob, born 1593, and then the last one, Hans, with no birth date, but he was married in 1578. I have lots of other information if you're interested. They're official records that I got when I lived there.
I'm also looking for pictures, stories, etc. Let me know if you're interested and I can email you the Family Group Sheets that I have been working on.
