Thank you for your quick reply. I regret to learn of the death of your sister, and I hope that all of her genealogical questions are now being answered. Thank you also for your kind offer to help. I took a look last evening at some of the original records and I found at least two Peter, or Johann Peter Klugs roughly in your time frame. Can you send me any details of the status of your sister's work on the ancestry and descendants of Peter Klug? I may be able to zero in on the person she was seeking, and send that info along to you. Again, my belated condolences.
