From a title meaning “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.
From the medieval name Genovefa, which is of uncertain origin. It could be derived from the Germanic elements kuni “kin, family” and wefa “wife, woman”. Alternatively it could be of Gaulish origin, from the related Celtic element genos “kin, family” combined with a second element of unknown meaning. This name was borne by Saint Geneviève, the patron saint of Paris, who inspired the city to resist the Huns in the 5th century.
