Henry Miller of Georgia

Am trying to find solid evidence concerning the parents of Henry Miller, born about 1825 in either NC or
Georgia. Married Annie McCarley (spelled McKerly on the marriage record) about 1844 in Campbell Co.,
Georgia. He is found in 1850 and 1860 in the same area. Children: William; Robert Alexander; Moses; Henry F.; John D. Henry died 1862 at the Battle of Bull Run. I would appreciate any information regarding his parents.
Thanks for your help. Charlene
