According to records in the Clan Akins Society Archives, there was an Adoniraum S. Akins who was a sergeant in Co. E, 25th North Carolina Infantry. Apparently judging by the Confederate military records there were no generals in the Confederate Army by the name of Aiken/Aikin/Akin/Akins, etc., although there were quite a number of Majors, Colonels, Sergents, Captains and Lieutenants, by all of these names.Adoniraum S. Akins was the only Confederate officer to bear the initials A.S. to have served in the Army. Interestingly enough there was also an Adoniram J. Akin who served in Co. H, 1st Regiment of Alabama Conscripted Soldiers. There were apparently no soldiers in the Confederate Army usingthe name Sims as a given name. I hope this may be of some help to you. Good luck in your search.
