In colonial times, Rene Laforce lived among other French Huguenots above the Falls on the James River in the rolling mountains of the Piedmont region. Some of his neighbors were CHASTAIN AND DUTOITS. His lands were located near "monacan indian town" (siouan tribe) on the south side of the James River just above what is today the town of Richmond, Virginia. With the subsequent county border changes, the lands today would be located in Powhatan County in and around Dutoy Creek and Manakin Town Ferry Rd.
On the other hand, the Pamunkey Indian Reservation is below the Falls, in the flatlands and due East of Richmond (about 30 miles). This reservation is located in King William County. It sits on the north side of the Pamunkey River and southwest of the town of Lanesville.
