Mairin ni Bhroanin was a female human of Irish descent who served in Starfleet in the 24th century. She served aboard the USS Gettysburg in 2323, and had befriended Ensigns David Gold and Augustus Bradford when they were assigned to that ship that year. By the early 2370s, ni Bhroanin had risen to the rank of Captain, and had been given command of the USS Huygens. She was killed in an engagement with the Klingons during the rift between the Klingon Empire and Federation in 2372-2373. Her death hit Gold hard, and led him to consider retirement from Starfleet.
