Sorry if this isn't the correct forum to post this. I'm wondering how you can find out what units were combined with others? I'm showing my relative was in the 1st Div. 1st Brig. 4th Reg. LA. Militia, but when I go to the Louisiana In The Civil War page on FamilySearch, they show no record of that unit. I've also searched the web for info on this unit and it shows that Theo Alonzo was Captain of this unit, but I can't seem to find much if any information on him. I do have the muster sheets that show the 1st Div. 1st Brig. 4th Reg. LA. Militia as well that I got from the Secretary of State in LA.
