First, a thanks to Greg for name & availability of Sheffer Family book. Will visit the FHC asap. I'm not sure the following is of much help, but it might lead to a source which might lead....etc. Vol. 3, part 2 of "Early Adventurers on the Western Waters" by Mary Kegley has a couple of pages on the Shaff(v)(f)ers. The source cited was "One of Wythe's Greatest Craftsman", Southwest Virginia Enterprise, January 1, 1988 by James C. Spraker who has apparently done a lot of research on the family. He also states that John was "believed to be a cousin" of Daniel and John George Frederick who were sons of Jacob and who also settled (at least temporarily) in Wythe County, VA. Kegley devotes most of her entry to John.....land records, Rev. War records, etc. By 1820, Daniel was in Wayne Co., Indiana where he died after 1830. Frederick moved to Greene Co., Tennessee & later to Clinton Co., Indiana. If anyone is interested, I have a little info on them/children/census. Happy hunting!
