The County was named for Thomas Sumter, who was a Revolutionary War officer. During the Civil War there was a skirmish at Dingle's Mill in Sumter County.

Research starting points
Census
Federal census schedules (and some state/colonial substitutes) are foundational for Sumter County household reconstruction. Start with every decade the family should appear, then correlate with land and probate.
Vital records
South Carolina statewide vital registration is comparatively late. For many Sumter County families you will rely on a mix of county probate, church registers, Bible records, newspapers, and delayed birth certificates—not only a single “vital records office” file.
Cemeteries
Cemetery surveys for Sumter County appear in published books, Find a Grave, USGenWeb archives, and local historical society vertical files. Always note whether a reading is complete or partial.
