Hi John, so good to hear from you. I have the 1954 Bishop/Woodworth genealogy book "The Descendants of Robert and John Poage" which focuses on the descendants of John, the younger brother. I'll do a little more research on your line, but John Poage's descendants definitely migrated to Ohio, Illinois and Indiana via Kentucky and (West)ern Virginia. In my book, I find that a James Poage, John's seventh child, was born 17 March 1752 and died in 1817. James' wife was Nancy or Anne Hogshead. They had seven children:John Gordon, Rebecca, Thomas, William, Anne, and James Moore. The name of the seventh child is not listed.
It may be that you are descended from Robert Poage the older brother. If so, you may need assistance from someone who has that book. It was available in reprint format. Check the internet to see if anyone has it as a reprint will cost about $150. Hope this helps, VB
