I have the CMSR for the Quitman Light Artillery and English's Battery, and Kerr was not in either command. Yes, there is a Quitman County in MS (or at least there was in the 1860's), but Natchez were both command organized is in Adams County (was and is the county seat. English was the 3rd Lt. in the Quitman Light Artillery and was promoted to Captain on Lovell's promotion.
