John and Eb Carron Character traits in Across Five Aprils

Ed Carron impetuously joins the war effort, and just as impertuously leaves it. Unfortunately, his dessertion leaves him guilt ridden. A seconf chance to rejoin the effort, granted by President Lincoln, allows Eb to redeem himself. From this, we can infer that he is a realist, who accepts responsibility for his actions.

John Carron? I see no evidence of a character by this name.
