My mother's family were small tradesmen in Augusta GA who immigrated from Scotland around the time the war began. Some of her maternal relatives fought in the war, but most were too old or too young. My father's family made up for it. Of my direct ancestors, Grandpa Long was in the 51st AL Cavalry (Partisan Rangers) under Col. Morgan, Grandpa Glover was a lieutenant in the 55th Alabama Infantry, and Grandpa Dent commanded Dent's Battery, Hindman's Div., Deas's Brigade. Also had a passel of cousins, uncles and assorted kinfolk in various Georgia and Alabama regiments.
It's interesting to look at the orders of battle -- because at the company level I'm related to or know most of the folks in my relatives' units. And it makes ya go hmmm sometimes -- for example this entry: John T. Stewart. Elected Captain on December 12, 1861. Not reelected, May 8, 1862. John Stewart married Grandpa Glover's oldest sister. He wasn't re-elected because he was killed at Shiloh.
They were from Walton County. Company F of the 16th Georgia was composed entirely of men from this county.
