Hi --
My gg-grandfather, Alexander Ewing Harris Jr., is (I believe) the AE Harris listed as a corporal with this unit (Company B out of Decatur GA). The commander was John T. Wimberly. I'm not entirely sure this is him, but it seems to me likely.
AE married Amanda Eliza Daniel, who was born in Georgia, and her parents were born in Georgia. Lots of Harrises and Daniel's...
Other than a few listings on the internet, I don't find any details on this unit. AE was a proud CSA veteran, which can be seen from his headstone (at findagrave.com - he is buried in AZ). His brother, a Gadsden County Florida veteran, was a member of a CSA camp and a representative to state conventions.
The Battalion commanders were Lieutenant Colonel Arthur Hood and Major Charles H. Camfield. Company B's commander is listed as John T. Wimberly. That's about all I know.
Any further information would be appreciated.
