Johanna

Johanna is the Latinate feminine form of Johannes, itself derived from the Hebrew name Yohanan, meaning God is gracious. The name spread throughout medieval Europe through the influence of Christianity, borne by several early saints and later by figures such as Johanna of Castile, queen of Spain in the early sixteenth century. It remains widely used across German, Scandinavian, Dutch, Finnish, and Hungarian traditions, reflecting its broad European diffusion. Related forms include Joanna, Hanna, Jana, and the Icelandic variant Jóhanna.
