Great! When you say Diellman, I bet your talking about the same guy I have as Johannes Dheilman. How wonderful to know when he came to America. Did he come over alone, do you know?
Do you know anything about your great grandparents? Robert Sr's parents, that is? The only Robert I have in my files is Robert Calvin, son of Joseph Dickensheet and Julie Bushnell, but he would have been born in the mid to late 1800's.
Thank you so much for your info, and I'll be sure to put this information in the web page (which I'm still working on.)
