Per gravemarker photo posted on Find A Grave by Sheep Lady & Sug, Elizabeth's date of death is February 18, 1922 rather than 1927. 1922 appears to be correct, as David's death certificate from 1923 states that he is widowed. However, I have been unable to locate a death certificate for Elizabeth.
David and Elizabeth are buried at Little Zion Methodist Church Cemetery in Marion County, SC and share a single gravemarker.
Also, there were several David Rogers from South Carolina in the Confederate Army during the American Civil War. I have been able to distinguish that this David Rogers was one of those soldiers and served in Gregg's Artillery under Captain M. B. Stanley.
Still seeking additional information.
