Thank you, Mr. Martin!
Yes, George Stallings was the only one of five brothers (who served) who was killed in action. He was killed at Monocacy Junction, MD, when a cannonball carried away his leg (as cited in George Watkins history of the 12th Georgia Light Artillery, Co F). He is in an unmarked grave there. It appears several Stallings served under that unit, as well. Other relations to Stallings were a James Atwell and Daniel Benjamin Stallings's future in law, Urbanis Dart of coastal Georgia.
Do you have any references or resources you could point to regarding Blodgett/Milledge Battery or W. Nelson's Artillery Battalion? I would be interested to find a battalion or unit history on the matter. Also, you mentioned the cards, which I have some from Georgia Archives, but not all (Ex. 1919 info...thanks much!) Is there a better way to obtain copies of these cards?
Thanks much for all you info and assistance.
