Richard Castillo

Richard Castillo was the helmsman of the Starfleet starship USS Enterprise (NCC-1701-C) at the time of its destruction in 2344. 

In an alternate timeline, during the battle with the Romulan warbirds over Narendra III, the Enterprise''-C was pulled through a temporal rift to the year 2366. In this timeline, created by their absence from Narendra III, the Klingons and Federation were fighting an extended war. When Captain Garrett was killed in battle with the Klingons, Castillo took command of the vessel. Under his command, the Enterprise-C returned through the temporal rift, restoring the timeline. Castillo's fate is unknown, though it is presumed he was killed by the Romulans.''

General Francis Castillo was a relative of Richard's on Francis' mother's side.
