What does the name Mollie mean?
Mollie is a spelling of Molly, pronounced the same way, so it shares Molly's meaning and origin.
Molly is a pet form of Mary, made from Moll with -y; Wiktionary calls it a diminutive of Mary with r changed to l. Wikipedia notes that this kind of change, also seen in Sally for Sarah and Dolly for Dorothy, dates from the Middle Ages, and that Molly grew out of an earlier pet form Mally. It has also served as a pet form of Margaret and Martha. Mary itself comes from Hebrew Miryam, whose meaning DMNES calls uncertain.
