Johanna

Johanna is the Latinate feminine form of Johannes, itself derived from the Hebrew name Yochanan, meaning God is gracious. It became widely used across medieval Europe through the influence of the New Testament and veneration of early Christian saints. The name has been borne by numerous historical figures, including Johanna of Castile, known as Juana la Loca, queen of the Spanish crown in the early sixteenth century. Closely related forms include Joanna, Jeanne, Joan, Jana, and the Icelandic variant Jóhanna.
