A single historic structure stands five miles north of Sylvania as the only evidence of the once booming town of Jacksonboro. And in its heyday, Jacksonboro was considered the most western frontier town of the United States. Named for the then governor of Georgia, Gen. James Jackson, the town held the county seat until a spring day in 1821 when the "curse" of a traveling preacher named Lorenzo Dow would change the face of the town forever.
