Magdalene
   a surname derived from Magdala, the place of her nativity, given
   to one of the Marys of the Gospels to distinguish her from the
   other Marys (Matt. 27:56, 61; 28:1, etc.). A mistaken notion has
   prevailed that this Mary was a woman of bad character, that she
   was the woman who is emphatically called "a sinner" (Luke
   7:36-50). (See MARY.)
   

Magdalene, a person from Magdala

MAGDALENE, n.  An inhabitant of Magdala.  Popularly, a woman found
out.  This definition of the word has the authority of ignorance, Mary
of Magdala being another person than the penitent woman mentioned by
St. Luke.  It has also the official sanction of the governments of
Great Britain and the United States.  In England the word is
pronounced Maudlin, whence maudlin, adjective, unpleasantly
sentimental.  With their Maudlin for Magdalene, and their Bedlam for
Bethlehem, the English may justly boast themselves the greatest of
revisers.
