[Jehanne]

Jehanne stands for Jehanne la Pucelle ("Joan of Arc", a name that she did not go by during her brief life, but likely arose from a poem that Christine de Pizan wrote that was called Le Ditie de Jehanne d'Arc); historians know more about the life of the Maid of Orleans than anyone in history who lived prior to her or anyone after for the next 300 years. I have always found that fact to be impressive. During her lifetime and for decades after her first name was likely pronounced disyllabic.
