This series was created when the title character of the 1956-58 TV series The Sheriff of Cochise (1956), a role also played by John Bromfield, accepted the position of U.S. Marshal based in Yuma, AZ.
After "U.S. Marshal" ended its run in 1960, both it and its predecessor series "The Sheriff of Cochise" were syndicated under the unified title "The Man from Cochise".
