Apparently not. I spent a couple of hours going down the 7th Alabama Cavalry and picking out the guys in Company B. I was impressed there is a great deal of duplication in the list, and no doubt in whatever source from which this data was derived. I doubt that 1900 individuals were ever on the rolls of the 7th Alabama Cav.
It certainly was helpful but a less laborious means of getting company rosters would be great. One has to use one's knowledge of how handwritten names are/were frequently misread to sort out the duplications.
