Each one of the men listed as 7th Alabama Cavalry that I checked belonged to Moreland's cavalry command, which was never numbered. I also found a member of the 5th Alabama Cavalry who was listed as 6th Alabama Cavalry Regt. Hopefully these errors can be corrected.

There are already two Alabama regiments reported as 7th Alabama Cavalry. We don't need another.

You can request copies of pension applications and service records here. The information that you have should be sufficient.
