Under Louisiana that should be Louis Hébert if you can add the accent, probably prop his brigade up a bit as he was the commander of the 3rd Louisiana and led his first brigade at the latest in early 1862 (identical with McNair's Arkansas (after Pea Ridge the unit is once again split up and two brigades are absolutely justified)).
Note for Missouri, are you sure all those brigades were regular ones? Most, possibly all are State Guard commanders and I thought some at least never transfered into Confederate Service. Though my knowledge of this area is limited to 1861/62 maybe early 63.
Great work though.
