I see an entry for a George K Warren in the Union Army. Is this a reference to Gouverneur K. Warren?

Govenerneur Warren was chief engineer in the Army of the Potomac, so he should certainly get the "Engineer" trait.
You might also consider giving him the "Signal_Cmd" trait, in homage to his work getting troops to Little Round Top on the second day of The Battle of Gettysburg.
