Hi--As an avid amateur genealogist myself, I had to rescue this book from a local store. It's "The Descendants of Robert and John Poage -John Poage Edition (Pioneer Settlers in Augusta County, VA". A genealogy based on the manuscript collections of Prof. Andrew Woods Williamson, Henry Martyn Williamson, and John Guy Bishop, supplemented and arranged by Robert Bell Woodworth, D.Sc. Privately printed by the McClure Printing Company, Staunton, VA 1954. There are several old letters tucked in the front of the book, including one from Mr Bishop.
I've listed the book on eBay. If you're interested in the book, please go to eBay and search for "Poage".
