Crewman J. Kelly was a crewmember aboard Enterprise NX-01 during its historic mission of exploration. In 2152, Kelly, along with Captain Archer, Commander Tucker, and Crewmen Rostov and Zabel, was captured and telepathically linked by an unknown alien entity which had infiltrated one of Enterprise's cargo bays. Eventually, Enterprise's communications officer, Hoshi Sato, was able to devise a means to communicate with the lifeform, which subsequently released the Enterprise crewmembers. (ENT: "Vox Sola")
