I looked at the index for Military Images Magazine for photos of soldiers in the units. Found none for the 52nd, four for the 11th, but it matters which 11th; there were four.
Georgia 11th Infantry Battalion
Georgia 11th Infantry Battalion, State Guard
Georgia 11th Infantry Regiment
Georgia 11th Infantry Regiment, State Guard.

Which were your ancestors in, or, better yet, what were their names, then I can locate the correct unit. I have every issue of MI.

I also have a copy of Sifakis' "Compendium of the Confederate Armies; South Carolina and Georgia". It lists their assignments, Field Officers and Battles they were involved in. If you would like a copy of the 3 unit details, send me an email address.
