I have searched both the NPS Soldiers & Sailors System and the Civil War Data Base.
Both list three Privates in the Hampton Legion Infantry: E/F in Co. I; J. A. in Co. H; and Moses in Co. A. No officers.
I have found two Captains in SC Infantry units: A. W. Pearson in Co. C, 7th Battalion SC Infantry and John H. Pearson, Co. G, 24th SC Infantry.
