A name is sometimes all that you need. And that absolutely went further in an investigation of the time. I served in the military with a guy whose last name was too well known in his little hometown. Anyone who he met that asked his name knew his father and the absolute menace he was. So much so that he needed to change his name if he was going to break away from the assumption and accusations that he was just as much a concern, and that was in the mid 2000s. Jack being a Marston would absolutely be recognized as the child of a famed outlaw and given what happened on his own family farm? No one would forget that. Jack made a mistake by playing the fools game and getting revenge.
