Timothy Lynch

Lynch was a 24th century Federation Starfleet crewmember aboard the USS Enterprise (NCC-1701-E).

During the Borg attempt to use time travel for the purposes of stopping humanity's first contact with Vulcans, Lynch was assimilated in 2161. The drone was one that pursued Captain Jean-Luc Picard and Lily Sloane into the The Big Goodbye holonovel. Picard used a Tommy gun to kill the drone and retrieve a neuroprocessor from the body. 

When in a private meeting later with Sloane, she accused Picard of not trying to save Lynch. This inspired Picard to rescue Data from the Borg.
