Karlyn
Feminine · “free man”
Karlyn is overwhelmingly a girls’ name — 2,385 girls against 7 boys since 1880.
Two suffixes competed to make women's names out of men's in mid-century America, and they came from different countries. The French -elle gave Janell and Danelle; the Welsh-derived -lyn gave Karlyn, Marilyn and Jolynn. Both were doing exactly the same job at the same time.
How old is the name Karlyn?
Karlyn first appears in US birth records in 1924 — 101 years ago. The typical Karlyn alive today was born around 1987, making them about 38 years old. About 2,100 people named Karlyn are estimated to be alive in the US today.
When was the name Karlyn most popular?
Karlyn peaked in 1968, reaching #1776 nationally. Today it ranks #6546, 4,770 places below that high. See the whole 1968 chart.

The story of Karlyn
American naming between about 1940 and 1975 needed a way to make women's names out of men's, and it had two tools. The French diminutive -elle and -ella came in through Janelle, Danielle and Rochelle; the -lyn family came in through Marilyn, Carolyn and Evelyn, where it was originally part of the word rather than a suffix, and then detached. Karlyn belongs to the second, taking a monosyllabic man's name and adding the ending, and the K spelling marks it as Scandinavian or German rather than French, which the Charles route would have suggested. Its best year in United States records is 1968.
Meaning
free man, with a modern suffix
Karl descends from Old Norse and Old High German karl, a free man or a man of the common people, the same word that gives Charles, Carlos and the English churl. The -lyn ending derives from Lynn, from a Welsh and English word for a pool, and carries no meaning. The compound therefore means a free man with a feminising suffix attached.

- counting every spelling
The SSA counts spellings, not names. Karlyn went to 17 girls in 2025, but Carlin, Carlyn and Karlynn and the rest below are the same name said out loud. Together the 5 spellings went to 57, which makes it the 903rd most-given girls’ name of the year — 5,643 places above the chart.
About 1 girl in 28,198 born in 2025 was given one of these spellings — against 1 in 94,545 for Karlyn 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

The Audria test
Every popular name lives one long story — a climb, a peak, a slow settling back. Karlyn's later chapters haven't been written yet, so we borrowed them: Audria climbed just as high around 1933, and its whole arc is on record. Line the two peaks up, and Audria's path sketches the road Karlyn is walking now.
