The Creek Indians long maintained settlements on the shoals of the Ocmulgee River, and Carolina fur trappers traded with them at a location known as the "Seven Islands of the Ocmulgee" as far back as the 1670s. The first non-Indians to settle in what became Jasper County arrived in the late eighteenth century. The first known white settler was a deer hunter known only by the name Newby, who lived near present-day Hillsboro as early as 1790. A treaty with the Creek nation that year provided land for a stagecoach route (the Seven Islands Stagecoach Road) from Augusta, Georgia, to Mobile, Alabama. Settlements grew up around the stagecoach stops.
