- You may be looking for the 23rd century Starfleet scientist Mira Romaine.
Mira (or Omicron Ceti) was the primary of the Mira planetary system. There was an inhabited planet, Omicron Ceti III, in this system. This planet was the location for a Federation colony in the 24th century. The system was located in the Alpha Quadrant. (TOS: "This Side of Paradise"; TNG: "Eye of the Beholder")
The connection between Mira and Omicron Ceti had not been established on screen. It was based on real world information and reference material. According to Star Trek: Star Charts (pg. 37), Mira (Omicron Ceti) was a Federation system in the late 24th century. This system was located in the Alpha Quadrant. The episode "This Side of Paradise", and the tactical situation monitor in "Yesterday's Enterprise", and "The Wounded" referred to this star as Omicron Ceti.
The star was depicted twice in the display. The tactical situation map depicted an area of space in the Alpha Quadrant. The locations Eminiar, Janus VI, Rigel, Andor, Babel, and Delta Vega were identified on "The Explored Galaxy" wall chart as being located in this quadrant.
