Thanks for your message. In the Ehmann book (of which I have only a photocopy as our family's copy was destroyed somehow when I was a child) I am Cb3IV.
Years ago, I copied out all the names in the book giving each person one line. This ran to 42 pp + 4 lines on European A4 paper (I was in England at university at the time). Counting just the descendants (not their spouses, unless they came into the family as a descendant in their own right) I got 1413 descendants of the Patriarch and his two successive wives. I wonder what this number would be now?
Best wishes for Christmas and the New Year, your kinsman, Richard
