The Matchotic Tribe, part of the Powhatan confederacy, inhabited the region between the Potomac and Rappahannock rivers, extending to mid-Richmond County, Virginia. This group included the Tauxenent, Potomac, Cuttatawomen, Pissasec, and Onawmanient tribes. In 1608, their warrior count was approximately 400; however, by the 1670s, this number had dwindled to just 60, as noted by Jefferson.
The Appomattoc, a tribe of the Powhatan confederacy located along the lower Appomattox River, Virginia, had 60 warriors in 1608 but became extinct by 1722. Their main village was burned by the English in 1611. The Chickahominy, another Powhatan tribe near the Chickahominy River, had estimates of 250 warriors in 1608 and formed an alliance with the English in 1613. By 1722, their numbers dwindled to about 80. Other tribes within the confederacy included the Matchotic and Weanoc, both experiencing significant population declines.
