Josephine “Joey” McKenzie was raised in the Unassigned Lands by her adopted father and grandmother. When her father went to prison, she took up bounty hunting under the guise and identity of “Joe Blackwolf”. Several years after taking up the gun, she was delivering a prisoner to the territorial courthouse in Guthrie, when, due to her reputation for ruthlessness, she was offered a position in the US Marshals service, which she accepted.

Some time later, she took a special assignment under cover to the town of Tidmoore and was introduced to Mac. Upon completion of the undercover assignment, she returned to her usual duty station of Waterloo, where she served as Town Marshal when not on assignment as a Federal Deputy Marshal.

Shortly after returning, she was shocked at the discovery that Mac was reassigned to being a Deputy At Large, stationed at the headquarters in the Territorial Capitol of Guthrie. She was even more shocked when he showed up in Waterloo, offering to help with keeping the peace when between assignments for the federal service.

Some time later, after several injuries and misadventures together, Mac and Joey wed. Finally Joey’s deception as Joe Blackwolf was discovered and she was accepted as co-town marshal with her husband, which they continue to serve, when not on assignment for the federal marshal service.
