Sabrina
Sabrina, the bewitchingly radiant name of a legendary Celtic goddess, is best known as the heroine of the eponymous film, originally played by Audrey Hepburn, and later as a teenage TV witch; it would make a distinctive alternative to the ultrapopular Samantha. Similar names you might also want to consider include Sabina and Serena.
In Milton's poem 'Comus', the river nymph is addressed as Sabrina Fair, which became the title of a 1954 play. In the original Charlie's Angels, Sabrina was played by Kate Jackson.
