Madd Jack, contact me. Seems we both have questions regarding John and Nancy's son James. I have been helping someone looking for James M. who is born ca. 1838 Ga. and md. 1867 in Terrell Co., Ga. but she was from Jasper Co., a Marium M. Comer d/o Jasper Co., Ga. resident George W. Comer. Death certificate says father is Augie. Know Francis' estate named grandson Augustus Malone-so--is this Augie a son of John A. and Nancy Hammock who in 1850 do have a James aged 10 in the Claiborne Co., La. census.
Is John "John Augustus?". That is my next un-educated guess. I know from your profile name you have been doing this as long as I have---so---contact me at rufuskin@bellsouth.net
