Greene S. Johnston was a prominent attorney and mayor of Statesboro. A marker on the home notes a construction date of 1887, but the Neoclassical appearance it exhibits today dates to 1914. My assumption is that the original house was simply modified by the addition of  the porch and portico. The Johnston family lived here until 1960 and it was used as a funeral home for many years thereafter. It is now a law office.
