Patrick Gibson was the name used by a USS Voyager crewmember in the holoprogram Fair Haven created by Tom Paris.
When Michael Sullivan used the Doctor's mobile emitter to visit the Voyager, he spotted two crewmen in the corridor, whom he recognized as Patrick Gibson and his cousin, Frank. Sullivan thought they worked on the wharf and said they visited his pub every Saturday night for the rings tournament. (VOY: "Spirit Folk")
It is possible, since other members of the Voyager crew used their real names while visiting Fair Haven, that "Patrick Gibson" might be the real name of this crewmember.
