John, My ancestor Captain James Harlow organized Company H 6th Georgia Cavalry. He had raised Company E in May 1862 and was forced to resign his commission due to illness. When he regained his health in 1863 he organized Co. H and resumed his commission. That late in the conflict, Summerville, GA where Co.H was formed, may have been the closest place to enlist. Summerville in Chattooga County, GA is just a few miles to the east of Cherokee County, AL.
You are the first person I've found who had an ancestor in either of the family companies. Will gladly share any info I have that could be of help.
