In Iberia the name eventually changed to the Spanish Juan, feminine Juana; in the medieval Portuguese it was Juo / Joane / Joan, now João (), feminine Joana, and also Ivo; in Galician, the orthography is Xan or Xoán, feminine Xoana. In Gaul, it became the Old French Jehan (the 16th century John Calvin still spelled his name "Jehan Cauvin") and later Jean (); the female form was Jehanne (the 15th century Joan of Arc still spelled her name "Jehanne") and later Jeanne. In the Occitano-Romance area, it became Joan (feminine, Joana) and Jan in Occitan and Catalan, from older Iouan and Iohan. In Ladin, it became Giuani.
