(covers information from several alternate timelines)
Frank was Human male Starfleet crewman who lived during the late 24th century. He served aboard the USS Voyager during the 2370s, where he was assigned to the command division while stranded in the Delta Quadrant.
In 2376, he was later walking with Patrick Gibson, when Michael Sullivan, who was wearing The Doctor's mobile emitter to visit Voyager, spotted them in the corridor, stating that recognized them as cousins who worked on the wharf, and visited his pub every Saturday night for the rings tournament. Janeway then explained that Sullivan "will find a lot of familiar faces on Voyager." (VOY: "Spirit Folk")
Background information Edit
This recurring character was played by an unknown background actor.
Frank was identified by name in "Fair Haven". It is assumed that like all of the other members of the Voyager crew who used their real names while visiting Fair Haven, that "Frank", too, was the real name of this crewmember. According to that episode's script, he and Patrick were identified as "two N.D. CREWMEN," further stating that "The crewmen react to Michael's presence, unsure how to respond."
