Construction of a grist mill and saw mill was in 1824-25. The lumber for Cedar Grove, the imposing mansion which James erected in 1831, was sawn at this site. A second mill, most likely situated at the location of the earlier facility, was built in 1844-46 by William Martin Sigman at a cost of $1,170. The frame millhouse, millstones, water wheel and other milling machinery survived into the twentieth century. Only the rock walls of the edifice continue to occupy the site. Portions of the millrace, originally bringing water from McDowell Creek to what was most probably an overshot wheel, are also extant.
