The story of Marilynn
Marilyn was coined in the early twentieth century by joining Mary to a fashionable ending, and it rose sharply in America through the 1930s and 1940s. Families produced Marilynn, Marylin and Marilynne as further spellings, and Marilynn peaked around 1946, at the height of the whole family.
Meaningscholars disagree
Not established
A compound of Mary and the -lyn ending, itself from Lynn — the Welsh llyn, 'lake' — or from Linda. Mary's own origin is unrecovered: proposals include the Egyptian mry, 'beloved', and Hebrew readings meaning 'bitter' or 'wished-for child'. Neither half resolves cleanly.

- counting every spelling
The SSA counts spellings, not names. Marilynn went to 41 girls in 2025, but Marilyn, Marylynn and Marylin and the rest below are the same name said out loud. Together the 5 spellings went to 431, which makes it the 566th most-given girls’ name of the year — 3,079 places above the chart.
About 1 girl in 3,729 born in 2025 was given one of these spellings — against 1 in 39,202 for Marilynn itself.
Spellings are grouped by a fixed rule that folds interchangeable English spellings of one sound (ck/k, ph/f, x/ks, a non-initial y for i) and keeps vowels apart, so Sean and Shawn stay separate names. It errs towards splitting: a family here is never larger than the truth. SSA national data, 2025. Method
