Molly

Molly is an English pet form of Mary, which derives from the Hebrew name Miryam, a name of debated meaning but often interpreted as meaning beloved, sea of bitterness, or drop of the sea. It developed during the medieval period as a common rhyming or diminutive nickname, following a pattern similar to the way Polly arose from Poll as a variant of Mary. The name has long been associated with Irish culture, where it remains a familiar and affectionate given name. Related forms include Mollie, Mary, Maria, and Moll.
