Now that Rock Hill had a name, a railroad station, and a post office, it began to draw more settlers to the area. Captain J. H. McGinnis built a small general store near the station in 1849 or 1850 to provide supplies for the construction and railroad workers. Templeton Black, who had leased the land to McGinnis, decided to devote some of his other adjacent land to building a larger town. He hired a local surveyor, Squire John Roddey, to organize a main street. Black sold his first plot of land along that street to Ira Ferguson for $125 a few weeks before the post office opened; other businessmen bought plots quickly after that.
