With the completion of the Harpeth Turnpike in 1844, now known as Wilson Pike, the hamlet of Rock Hill grew into the commercial center for a large surrounding area. The original store and post office stood 350 yards south at the driveway entrance to the George Pollard house. Beyond the store, near the Pollard-Tulloss graveyard, stood a steam cotton gin operated by Pollard and Tom Tulloss. The turnpike's southern-most tollgate stood at the junction with Starnes' Mill (Shag Rag) Road, and near the entrance to Burke Hollow Rd were a blacksmith shop and sawmill. At this site Rock Hill's second store was built in 1896, operated for many years by S.R. Lamb, and burned in 1954.
