I have saved the 1st S.C. until last, because it is so confusing. The 1 S.C. included the 1 S.C. Regulars, an artillery unit, the 1 S.C. (McG+Creary's), the 1 S.C. (Hagood's), and often the unit designator is left off on tommbstones for units such as "Militia," "reserves," etc.
I post these as they appear on the tombstones, without cross-checking the names against rosters.
