Meaning and history
Molly is a medieval diminutive of Mary that is now often used as an independent name. It developed from the earlier diminutives Malle and Molle, and James Joyce used it for Molly Bloom, the wife of the main character in Ulysses (1922).
Molly rose from #208 to #196 for girls between 2024 and 2025. Its highest annual birth count came in 1991, with 4,652 births.
