A loyal follower of John Frederick Paxton who works at the Orpheus mining facility on the Moon and helps guard the captured Trip Tucker and T'Pol.
Josiah is a member of Terra Prime in the Enterprise episodes Demons and Terra Prime. He is one of the miners at the Orpheus lunar colony, which Paxton uses as cover for his movement.
When Trip Tucker and T'Pol infiltrate the mine posing as new workers, Josiah is among the men they must deceive. After the pair are exposed, he travels with Paxton when the entire facility lifts off and flies to Mars to seize the verteron array.
Josiah remains at his post as Paxton threatens Starfleet Command. A committed believer in keeping Earth for humans alone, he is among the followers still with Paxton when Jonathan Archer's team storms the control room and ends the crisis.
