The story of Fallyn
The Ó Fallamhain were a Connacht family and the surname anglicized as Fallon. It reached America with Irish emigration. Its use as a given name for girls follows a 1980s television character almost entirely, and Fallyn, Falon and Fallon are the spellings from that wave. The English word fallen is a coincidence and an unfortunate one.

Spellings of Fallyn

- Fallyn on the 2025 chart
- #888
- counting every spelling
The SSA counts spellings, not names. Fallyn went to 33 girls in 2025, but Falynn and Falyn are the same name said out loud. Together the 3 spellings went to 72, which makes it the 888th most-given girls’ name of the year — 3,377 places above the chart.
About 1 girl in 22,323 born in 2025 was given one of these spellings — against 1 in 48,705 for Fallyn 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
