Jamie Finney was a female Human civilian in the 23rd century. Born in the 2250s, she was the daughter of Lieutenant Commander Benjamin Finney. She was named after Finney's former friend James T. Kirk.
In 2267, when it was believed that her father was killed through Captain Kirk's negligence, Jamie accused Kirk of murdering her father. She later rescinded her accusation, after reading letters sent to her and her mother that revealed the closeness of the friendship between the two men, and tried to protect Kirk from losing his command.
When it was revealed that Ben Finney was still alive and that he had merely framed Kirk for his death as an act of revenge, Kirk had Jamie brought up to the USS Enterprise in hopes that her presence would make Finney easier to handle. Hiding in engineering, Finney sabotaged the ship's engines, causing its orbit to decay. When Kirk informed Finney that Jamie was aboard and she would also be killed, Finney broke down and, after being subdued, he told Kirk the area he sabotaged, preventing the ship's destruction.
