What is "wanchese"

Wanchese was the last known ruler of the Roanoke Native American tribe encountered by English colonists in the late sixteenth century. Along with Chief Manteo he travelled to London in 1584, where the two men created a sensation at court. Hosted at Durham House by the explorer and courtier Sir Walter Raleigh, he and Manteo assisted the scientist Thomas Harriot with the job of deciphering and learning the Carolina Algonquian language. Unlike Manteo, Wanchese evinced little interest in learning English, and did not befriend his hosts, remaining suspicious of English motives in the New World. In April 1586, having returned to Roanoke, he finally ended his good relations with the English, leaving Manteo as the colonists' sole Indian ally.
