J. D. Elder's great-grandfather, Patriot William Elder, was probably guided
by a map like this. (Click above image for clearer view)
William Elder, and his brothers, trip from Spartansburg, South Carolina,
as recalled by a descendant:
"coming over the mountains to the Holston River and down that and the
Tennessee in a flat boat to the Ohio. Up that river and the Cumberland by poling
the boat until opposite this place" (Today's Dycusburg).
