Meaning & origin

Marylyn is a compound name that blends Mary with the suffix -lyn, part of a trend that flourished in early 20th-century America. First recorded in 1910, it reached its highest popularity in 1936, with an estimated 1 in 229,610 births using the name in 2025. The name's trajectory has been stable in recent decades, never experiencing a revival. While no states stand out as top locations for Marylyn, it has a classic mid-century feel. The name combines the enduring appeal of Mary with the fashionable -lyn ending, making it a distinctive yet familiar choice.

Marylyn is a modern combination of the name Mary, from Hebrew Miriam meaning 'drop of the sea' or 'beloved', and the popular suffix -lyn (from Lynn, derived from Welsh llyn 'lake'). It emerged in the early 20th century alongside similar blended names. The name saw its peak usage in the 1930s in the United States.
