Yes. 1st AL Cavalry Regiment, for example, has B.K. Schoggins, Blacksmith; W. J. Tompkins, Blacksmith; W.H. Jaynes, Blacksmith; and then W.M. Hamilton, Farrier; H.F. Nails, Farrier; and Hiram Millsap, Farrier. These men were not in the same company, but in the same regiment (at the same time? Don't know). Were there regulations or "standard practices" covering this?
