I don't know if there was a forced march in 1849. I know that my Princes came from
GA to Eastern AR right about that time. I had a 2g uncle born 1845 in
GA and my 2g g'ma was born here about 1849. Her grandparents apparently came between 1830 and 1832. Her mother was Cherokee and possibly others in the line. Do you have an
Ajax Tyner/Tyre in your info? Other families in this line:
Hydrick,
Barnes,
Cooper, I think maybe Mitchell. Some of these families were in
McNairy and surrounding counties of TN about 1830.
