Several ships named after Florence Nightingale bore this designation during Era-1 (all but one were hospital ships).  The most famous of these was the one that closed the Era. 

During the Great Reckoning, the Nightingale was dispatched to the planet Aldebaran 2 under the authority of the Tardigrades with the mission of evacuating the most productive and prominent scientists and academics before the Holy Empire of Man could reach the planet.  The refugees aboard the Nightingale helped to form the foundation of what was to become the Galactic Republic.
