There is a tremendous amount of interest in this subject and I have found a few of you with good information about the Nyhan family. I do not expect to have much time until July 2010 to begin putting this together, but if you have any information you are willing to share, please email it to me at firstname.lastname@example.org with whatever names, dates of birth, locations, etc. I will try to compile using some kind of standard nomenclature. Please stop by again. Thank you for your interest!
