 The Pee Dee tribes (such as the Beaver Creek Indians and the Pee Dee Indian Nation of Beaver Creek) traditionally occupied land between the two forks of the Edisto River in Orangeburg County, and especially along Beaver Creek, as did their ancestors for thousands of years before European encounter.Their original language family was Siouan.English colonial accounts from the 18th century acknowledge the Pee Dee peoples in this area.
