Formed in 1888 from Clarendon County, Darlington County, Marion County and Williamsburg County

An old deed may name a county that no longer exists, or a boundary that has since moved.

Florence County was created from Clarendon, Darlington, Marion, and Williamsburg counties. The county gained territory from Darlington in 1889, and gained land from Williamsburg multiple times between 1904 and 1921.
