Well, there's a J. B. Grice listed for Co. "H" of the 8th AL Cavalry in the Broadfoot listing, but there were actually two different 8th AL Cavalry regiments, Ball's-Hatch's was one, and Livingston's was the other. No indication of which unit Grice was in, and there are no other listings. (Probably the listing for the "8th Cavalry" in Broadfoot is a compilation of men from both units.)
