This name is borne by a Jewish woman in Walter Scott's novel Ivanhoe (1819), as well as the title character (who is deceased and unseen) in Daphne du Maurier's novel Rebecca (1938).
The name was common in France during the Middle Ages, and was introduced from there to England, though it eventually became rare. Interest in it was revived by the character Melanie Wilkes from the novel Gone with the Wind (1936) and the subsequent movie adaptation (1939).
