History & Origin

Molly emerged in medieval England as a pet form of Mary (via the rhyming substitution Mol/Moll) and also of Margaret. Mary derives from Hebrew Miriam, whose meaning is debated but often given as 'sea of bitterness,' 'beloved,' or 'wished-for child.' Molly appears in English ballads and folklore from the 17th century onward, including the famous song 'Good Molly Malone.'

Molly was a top name in England and Ireland from the 17th through 19th centuries, declined in the early 20th, and has enjoyed a robust revival since the 1980s. It ranks consistently in the top 100 in the United States, the United Kingdom, Ireland, and Australia. Its cheerful, approachable sound gives it timeless appeal.

Did you know? In 18th-century English slang, 'molly' was a term for a kept woman or an effeminate man — a usage that has completely vanished, leaving the name entirely positive today.
