I hope you have got your family book until now. I was looking around in the net and found your question there. I a rheinganz from germany, the line which changes from s to z about a century ago. but I am interested in the family history. Unfortunately my grand uncle's family book was destroyed at the end of WWII. So I kindly asked you to send me a copy of yours to help me strat a new book.
Thank you very much and I am waiting for your answer. Kind regards Ursula
