From a title which meant "of Magdala". Mary Magdalene, a character in the New Testament, was named thus because she was from Magdala - a village on the Sea of Galilee whose name meant "tower" in Hebrew. She was cleaned of evil spirits by Jesus and then remained with him during his ministry, witnessing the crucifixion and the resurrection. She was a popular saint in the Middle Ages, and the name became common then. In England it is traditionally rendered Madeline, while Magdalene or Magdalen is the learned form.
