There are 2 John M. Andersons on the 1860 census in Richmond County, Georgia. I am looking for their CSA service. One is a GGGGrandfather and the other a GGGUncle (?) I believe so far. I have a John M. Anderson, from Lillian Henserson's book, as a Pvt in the 21st GA Inf Co. B. The J.M. Anderson in Cobbs Legion Co. C. is not one of mine. Any help would a appreciated.
