James McParlan a.k.a. James McKenna. Born in County Armagh, Ireland, in Mullbrack in 1844. He spent 44 months infiltrating the Molly Maguires, gaining information. After testifying against many Mollies, being the catalyst which sent them to the gallows, he continued his work with Alan Pinkerton's detective agency without much ado except for the unravelling of the assasination of the Wisconsin governor. He eventually died in Denver, Colorado in 1919.
