I found this photo of a 6-teacher school in Edgefield County in Carter Woodson’s The Rural Negro, but the name of the school was not given, just the county. The Rosenwald Database is down until Summer 2023. According to the South Carolina Department of Archives and History, Edgefield County had two 6-teacher schools, the Edgefield School and the Johnston School. Please let me know if you are able to confirm which one it was.
