Morgan has long been a traditional Welsh male name whose most notable female antecedent is Morgan le Fay, King Arthur's half sister and a famed sorceress in Arthurian legend. In this country, Morgan is now used more for girls than boys, though considerably lower than its Top 25 status in the 1990's.
And although it's been veering south for both sexes, we still find Morgan a sophisticated choice.
Morgan le Fay reappears as a sorceress in Mark Twain's A Connecticut Yankee in King Arthur's Court.
Actress Morgan Fairchild--who had an influence on the name's popularity for girls-- was born Patsy.
