There was a television series called "U.S. Marshal," which aired from 1958 to 1960. The show starred John Bromfield as U.S. Marshal Frank Morgan, who worked in the Arizona Territory in the late 19th century.

The show followed Morgan as he traveled around the territory, tracking down fugitives and maintaining law and order. He was assisted in his duties by Deputy Clay Forester, played by Ron Hayes. The show was notable for its realistic portrayal of life in the Old West and its emphasis on action and adventure.

Despite its popularity with audiences, "U.S. Marshal" was canceled after two seasons due to creative differences between the producers and the network. However, the show remains a classic example of the Western genre and is fondly remembered by fans.
