As best I can determine from limited sources, this was the home of Dr. William Benjamin Johnson Hardman (23 November 1822-21 August 1904), the father of Governor Lamartine Hardman, who was also a physician. The elder Dr. Hardman was one of the most prominent and best-known citizens of Harmony Grove (changed to Commerce in 1909).  Dr. Hardman served in Deadwyler’s Company, 4th Georgia Cavalry.
