An historic resource survey dates this structure to circa 1935. I haven’t found any other information so far.

Since 2008. A visual survey of Georgia's historic architecture and culture. 9,000 locations. 30,000 images.
The local or state archives, or the church entity that originally oversaw construction of, or governed this church may know where records of the church’s history could be found. My mother-in-law lived in Johnson County for a while when she was a child. She & siblings occasionally picked cotton or other crops to help support their family in the 1930s. Her maiden name was Hammock.
