It seems you are very knowledgeable on the Abernathy line. I have been working from time to time on this for about 20 years. My ancestor is Joseph Abernathy of Pocahontas Missouri. (I'm not going to get into the Pocahontas debate as to the Indian connection.) I have the Abernathy's back to George Abernathy de Barrie also, but I'm not sure of the accuracy. I have tried to get the book by Arvord Milner. You cannot get it interlibrary loan. I have found Don Roth's Home Page on Genealogy.com. Are you familiar with this and is his information the same as the Abernethy Book? I am assuming that Joseph's father was Robert, although there is some debate about that, some think it was David. Is it possible to get this book or the Robert Lineage part of it? By the way I also have a copy of the letters written to Joseph Abernathy from his brothers in North Carolina. I have a lot of Abernathy information in Cape Girardeau if there is anything you need. Thanks.
