Nora

From Memory Alpha, the free Star Trek reference

Nora was a female crewmember aboard the ECS Horizon. She and Travis Mayweather grew up together aboard the ship during the early 22nd century.

Nora and Travis reunited when he visited the Horizon after the death of his father. She told Travis that his brother Paul might not be ready to be captain. That the ship had lost contacts when goods were delivered late, and that the crew was losing confidence in him. She agreed with Travis that the Horizon should be modified in order to meet the threats from pirates. (ENT: "Horizon")

Nora and Travis may have had a romantic attraction to each other, although this was never fully disclosed on-screen. She was played by actress Nicole Forester.
