A new railroad station in this location in 1883 was called "Jump Off Joe" for a local stream. The station was renamed "Merlin" in October 1886. The name came from a railroad civil engineer who named it for the merlins (a type of falcon) he saw in the area. "McAllister" post office was established about a mile north of Merlin in 1885, then moved to the vicinity of the railroad station and renamed Merlin in 1891.
