Thanks for your help. I do refer to the 3rd Alabama Reserve Regiment. Any information sources for that regiment would be great!

The different designations of Alabama troops (ie. militia, home guard, reserve, local troops, &c) perhaps account for my mistake. It sounds like reserves retained their state designation until reaching 18. Senior reserves would never receive a regular designation. That makes any reference to 64th and 65th Alabama infantry regiments appear unusual. Are Alabama reserves (state militia (class 2)) and Confederate reserves the same thing?

Thanks for sharing your knowledge. I am new to this message board. Forgive my enthusiasm. I will check and get back to you with my sources.
