The origins of Necotowance are unknown, his first historical appearance was in October, 1646. After surrendering to the English, Necotowance signed a peace treaty with the General Assembly of Virginia which ended the Third Anglo-Powhatan War(1644-1646). In the Assembly he was identified as "Necotowance, king of the Indians," the successor of Opechancanough, Chief of Tsenacommacah and appears to have been the chief of all the neighboring tribes on the south as well as the north side of the river.
