Before the Gaw family made their way to Jackson County, Tennessee, they were in South Carolina. My 7th-great-grandfather John Gaw died in Abbeville County, South Carolina sometime before October 1788. This was part of the old Ninety-Six District. From the Internet Archive's Wayback Machine, a map of the Ninety-Six District shows the area covered a five-county region in the northwest corner of the state.
Greenville County, South Carolina, which also features in the history of the Gaw family, was created out of the original Indian land shown in the 1785 map. Below is another map showing South Carolina's districts and counties between 1791-1799.
