I first photographed this historic church in early 2009. History regarding the congregation or structure is hard to come by, but Methodist archives indicate the present structure was built before 1863. This suggests that it was built before the Civil War, as little construction was going on at that time.
There is a bit more history at http://hrcga.org/powelton-methodist-hancock-5/
A scene in the 2009 movie Get Low (which starred Robert Duvall, Sissy Spacek and Bill Murray) was filmed in the historic church cemetery.
