Since you did not give any dates, I am not sure about the persons you mention but I will try.I also have family members from Macon Co, GA. My Great-great grand father was John B. Odom (b. 1828 - d. 1881) who was married to Sarah Law (1833 - 1907).He had a younger brother named Dempsey Odom (b.184? - d. ? ).Dempsey was married to Martha Bishop (b.1853 - d.?). John B. and Dempsey had 3 other brothers and 1 sister: Abraham Odom (1830 - 1903), Joshua Odom (1835 - 1909), R. Shepherd Odom (1838? - 1883), and Mary Ann Odom (1849? - 1900). These were the children of Willis Odom (1808 - 1886)and Sarah King (b.1808 - d. ?). Willis and Sarah King Odom were married in Jones County, GA and later moved to Macon Co. GA. They are supposedly buried in the Odom Cemetery in Macon County but it is unmarked. I have not gone back any further than this with much success.Hope this is helpful.
