Janet

Janet is an English diminutive of Jane, itself the feminine form of John, which derives from the Hebrew name Yohanan meaning God is gracious. The name was common in medieval Scotland and England, where it functioned as an independent given name rather than merely a pet form. It gained widespread use across the English-speaking world through the nineteenth and twentieth centuries. Related forms include Janette, Janetta, and the Scottish Gaelic Seònaid.
