Krystine Marie Leone was a Starfleet officer. She served during the 24th century, from 2349 until at least 2366. In 2365, she was promoted to the rank of captain and placed in command of the USS Farragut (NCC-60597). (Star Trek: Full Speed Ahead)
Krystine Marie Leone was born an only child to Starfleet Lieutenants Patrice and Angelina Leone in the early morning hours of April 7, 2328. Raised as a child of Starfleet officer, Krystine spent a majority of her life moving from post to post with her father, who served as a communications specialist for different Starbases in the core systems. Her mother led the life of a starship officer and beyond the few months spent after giving birth, she returned to her ship and her career. While Krystine spent a majority of her early life with her father and his family, she always looked toward her mother for inspiration in career choice. Entrance to Starfleet Academy was the pre-determined path for their child, and her studies were aligned with that objective in mind.
