How Columbia came to be
From Wikipedia’s history of Columbia.
Columbia is the county seat of Marion County, which was created out of Amite County in 1811, encompassing the southwest quarter of the current state of Mississippi. Before statehood in 1816, there were three territorial census/poll tax records taken of what was deemed Marion County at the time. These records reveal that during 1813, several Lott men arrived and settled on the Pearl River in what is now Columbia. In 1813, William Lott was the largest slave holder near present-day Columbia, owning 28 people. Five mensettled south of present-day Columbia on 2,789 acres (1,129 ha) of land with 65 enslaved people. North of present-day Columbia, on what was the earliest attempt at a town, Timothy Terrell enslaved 32 people on 3,151 acres (1,275 ha).
