Folks,
My name is Nicholas and I live in Southern Maryland. I am doing some research and am wondering if anyone has info on George A. Groves from Frederick County, Virginia. Particularly his Confederate Army Service during the Civil War. He commanded a battery of the 1st VA light artillery entering the army as a captain, and I know little beyond that he fought at 1st Manassas then was in detached service and continued to the end if the war. In a nutshell, I am looking for the following-

-Death date (1902?) and place
-Burial /gravesite
-Final rank in CS Army
-Occupation after war

Anything would be greatly appreciated folks! Thank you so much, best regards!
