Carole, et al.; I'm familiar with RNA/DNA analysis due to the legal issues I've addressed related to it. So some food for thought. I have a few thoughts and suggestions that I thought I should mention due to the significance of the information an RNA/DNA analysis provides. I recall a university professor in England who contributed for a study and he subsequently discovered he was a direct descendant of a man whose corpse was discovered in an ancient burial site just miles from where the professor resided. You may recall the recent DNA analysis of blood/hair follicles from Thomas Jefferson and the ramifications to a few families. Certainly, such an analysis can produce accurate information. Sure, John Dutton was no Thomas Jefferson and the results won't change world history. However, it may create "issues" for some Dutton families in-so-far as confusion over how these contributions occurred. It may create more questions than answers. Let's assume an analysis indicates that a Pennsylvania Dutton is related to an ancient English Dutton. Such proof provides only a genetic link. A link, it must be considered, that may exist in every Dutton in the world. Restricting the study to one branch and not all invalidates its validity. California Duttons may carry the same DNA sequences. Assuming they weren't related, Ohio Duttons may be related to Pa. Duttons and not know how this happened. With such "proof," no one would yet have any further information as to how these contributions came about. Who were these mysterious links? Does the "proof" validate suspected links? No, because the genetic link may have come from a different contributor who married into his or her family. The marriage of cousins was not uncommon. Even a distant cousin, not even known to be a cousin, could contribute the genes discovered. Ultimately, the DNA sequences of the various U.S. and English Dutton tribes are irrelevant without ties or links made from history of substance to bind the tomes together. Its most likely that the refined DNA sequencing necessary to distinguish one genetically linked Dutton tribe from another and yet from another would take years and cost tens of thousands. The less analytic tests would serve no purpose. The latter are virtually as unhelpful as blood types when this question of intrafamily links is asked. Perhaps some might form a nonprofit corporation, raise funds via donations, grants, and other means, and some day retain a medical facility to handle the task. I don't think its going to happen on a shoestring. With respect and compliments for an interesting idea. Walter
