UN-known CW Soldier ~ Does He Look Like Your Ancestor?

I saw this photo posted on the Gettysburg Museum of History's facebook wall. I assume they have no name for this young soldier. But somewhere there may be someone who recognizes him from other old photos. I wonder if Face Recognition software could be used to match up nameless old photos with relatives/descendants old photos. Hopefully.
So I am posting it here, because you just never know.
