Martin was born on March 5th, in 2345 at Starbase 39-Sierra along the Romulan Neutral Zone.
During William Riker's last night on the Hood, he and Brianna had a one-night stand.
The Hood attempted to mediate a dispute on Balarin II in 2364. Brianna made heroic efforts to save some representatives of the meeting when the gathering was targeted by one of the factions. For her actions, she was awarded the Prentares Ribbon of Commendation and promoted to full Lieutenant; once promoted she chose a security position.
In 2369, Brianna earned the Extended Tour Ribbon and a promotion to Lieutenant Commander. She was reassigned to the USS Pathfinder.
In 2369, Commander Martin services on board the USS Pathfinder a vessel that is on border patrol along the Romulan Neutral Zone that gave Brianna time to see her mother while the ship was next to the starbase.
