Martin L. Ruff, prominent pioneer settler of Cobb County, and his descendants operated the wheat-and-corn grist mill through most of the century.

Although the grist millʼs fieldstone facade was pockmarked with bullets, still visible today, the dwelling was spared from torching when it was designated to serve as a field hospital for the many wounded combatants.

The Millerʼs House was constructed in a simple architectural style featuring a distinctive tall, narrow profile that is identified by preservationists as Plantation Plain.

Two successive bridges were erected at the same location on land owned by Martin L. Ruff, Sr., a prominent early settler in this district of Cobb County, whose family members operated the adjacent grist mill.
