Marguerite Clark was a female Human Starfleet ensign in the 24th century. Clark served on Deep Space 9 and the USS Defiant.
Clark was assigned to the new DS9 when it became operational in 2385, straight out of Starfleet Academy. Although from Earth, Clark had a transitory accent that Wheeler Stinson could not place and not one from the Sol system. Clark operated the transporter when the Defiant responded to the Ohalavaru attack on Endalla. (DS9 novel: Sacraments of Fire)
