Situated between the Cumberland Plateau and the Tennessee River in southeastern Tennessee, Marion County was established in 1817 from former Cherokee lands and named for Revolutionary War brigadier general Francis Marion. Its county seat is Jasper. Across two centuries the county's story has included Cherokee Lower Towns, Civil War engagements, iron furnaces and coal mines, TVA dams, a silent-film actress from South Pittsburg, and a Holocaust memorial assembled by middle schoolers in Whitwell.
What's New?
The Old South Pittsburg Hospital
From the town's 1959 municipal hospital to a paranormal research center: the doctors who came before it, the move to Jasper, and the building's years on ghost-hunting television.
Early Baseball
Before high-school football, the county's teams were company teams: a cement-plant diamond built in 1907, the Hales Bar construction village's club at Guild, and an April 1912 game its supporters reached by steamboat, 219 of them.
Hale's Bar Village
A new section on life in the construction villages: families raised in company housing at Guild, one family's move from a Whiteside coal mine to the dam, and the ball club the villages fielded.
Elections & County Commission
The county Democratic convention of April 1912, reconstructed from the newspaper: the resolutions, the instruction for Judson Harmon, and the full sixty-seven-name delegate roster.
