On the upper Potomac, Smith found that some of the Indian groups were friendly and others not. One they found friendly were the Moyaons, who lived on Piscataway Creek. They were the central tribe in the Piscataway paramount chiefdom, and the enemy of the Powhatan. In assessing the native peoples, Smith estimated the populations by focusing on the number of men of adult age who could be considered warriors. From his count of 100 at Moyawance, we can conclude that the village must have had an overall population of 400 to 500 people. Piscataway Creek offered good land for agriculture, rich marshes with edible plants, abundant fish and waterfowl.
