Juana

Juana is the Spanish feminine form of Juan, which itself derives from the Latin Iohannes, rooted in the Hebrew name Yohanan meaning God is gracious. The name was borne notably by Juana I of Castile, the sixteenth-century queen known as Juana la Loca, whose reign shaped the course of Spanish imperial history. Related forms include the masculine Juan, the Portuguese Joana, and the English Joan and Jane.
