Several years ago when I found the Odom Cemetery in Macon Co. GA, I also found the Kelley Cemetery. In it were the graves of Ed Odom, Reuben Odom, Nancy Odom, Dora Irene Odom and Lester Odom. I had concluded that they were related to Dempsey Odom because Dempsey's wife, Martha Bishop (b. 1853 in SC)is shown living with Louisa Bishop (b.1827 in SC) in the home of David M. Kelley (also born in SC)in the 1860 census. I haven't researched this family as much as the John B. Odom (Dempsey's older brother)family. But any info that you find will be much appreciated. In your research you might want to spend some time in the Washington Memorial Library in Macon, GA.There is a wealth of information there that will be useful in your search.
