October 18, 1770 | Treaty Treaty of Lochaber Continued consternation over the exact location of boundary between the Cherokee nation and Virginia led to this 1770 settlement of the line. At issue was a contested swath of land that had been ceded to the Indians at Hard Labor. The new agreement adjusted the border to give lands east of a line running from the Holston River to the convergence of the Great Canaway (Great Kanawha) and Ohio Rivers to the British province of Virginia.
