I know it’s a long shot, but it would be so cool if they could extract DNA and identify the family lines of the buried. So often there was no surviving record of those killed unless it was a general or other commanding officer. My own ancestor was at Hobkirk Hill the following year and the only reason I know this is because another man mentioned him in his pension application as having been granted a temporary promotion for the battle.
I have my great grand fathers Civil War Discharge hanging on my military wall, kinda cool. Richard Mc was the 4th generation in America; a David was kicked out of Scotland and made to Maryland in late 1600s. I'm the 11th generation and in Alaska.
I've seen the family bible from 1702 and they often had 2 wives each having 15 kids. 1/3 of the kids died from consumption (TB). We have it easy nowadays.
