Meaning & origin
Mollie first appeared in U.S. birth records in 1880, the same year it reached its peak rank of 1113th (a rank that, due to the smaller population of the era, represented a much higher proportion of births than today). Since then, the name's popularity has followed a falling trajectory, with a noticeable decline beginning around 1991. In 2025, approximately 1 in 7,581 newborn girls received the name, placing it well outside the top 1000 most popular names. Regionally, Mollie has had its strongest presence in southern states, particularly Mississippi, Louisiana, and Kentucky, reflecting its ongoing regional character.
Mollie is a spelling variant of Molly, which originated as a diminutive of Mary. Mary, from Hebrew Miryam, has an uncertain etymology but has been associated with meanings such as 'bitter' and 'beloved' over the centuries. Molly became a standard standalone name especially in the 18th century, and Mollie emerged as an alternative spelling in the 19th century, particularly in the United States.
