I'm talking about the guy who owns the farm, where the munitions were stashed. I thought Pitcairn called him James Barnes. I suppose that would have made it, 'Barnes's Barn'!
Oh, I thought you meant the actor. I think the character was named James Barrett...Barrett's Farm was outside of Concord.......but I can't find him on imdb, or on the History Channel's website, either. Fairly important character, to not even be listed as "uncredited" or anything! I searched for the character name both places, but nothing. Sorry for the confusion!
I absolutely agree.........no matter what they thought about the actor (whom I thought was very good), the character is hugely important to the Revolution's history. If I can ever figure out who the actor is, I'll post it back!
