I too am researching the Blodgett/Milledge (3rd GA Artillery) Battery. I also LIVE IN OHIO (Akron area)!
My g-g Grandfather was William Henry Stallings of Augusta,GA who served in the Battery. They then settled in Macon area before moving to Kentucky, then Ohio.
I've been trying to trace his movements in the War, and after. For instance, trying to find a burial site.
Would you be interested in corresponding to compare notes on the Blodgett/Milledge Artillery Battery?
