Finnegan
Masculine · Irish roots · “fair-haired”
Finnegan is overwhelmingly a boys’ name — 13,011 boys against 104 girls since 1880.
Finnegan began as an Irish family name — Ó Fionnagáin, the descendants of a man called Fionnagán, "the fair little one." It traveled to America on emigrant ships and into a 19th-century music-hall ballad, "Finnegan's Wake," about Tim Finnegan and a splash of whiskey; James Joyce borrowed the title, dropped the apostrophe, and made it one of the strangest books in English. Said aloud it has three easy beats and folds down to Finn without effort.

The story of Finnegan
The root is the Irish word fionn, fair or bright, the same element behind Fionn mac Cumhaill of the old Irish tales and behind the plain modern name Finn. Add the diminutive endings and you get Fionnagán, a personal name that hardened into the surname Ó Fionnagáin, anglicized as Finnegan and long associated with counties in the Irish midlands and west. Emigration carried it into American and Australian phone books, and the 19th-century comic ballad "Finnegan's Wake" carried it into song — the source of the title Joyce reused for his 1939 novel. Its use as a first name, like Riley and Sullivan before it, belongs to the recent American habit of promoting Irish surnames to the front of the name.
Meaning
fair-haired, from a diminutive of Irish fionn "fair, white"
The surname Ó Fionnagáin means "descendant of Fionnagán"; Fionnagán is itself a double diminutive of fionn, "fair" or "bright" — so, roughly, "little fair one."

Every popular name lives one long story — a climb, a peak, a slow settling back. Finnegan's later chapters haven't been written yet, so we borrowed them: Duncan climbed just as high around 1997, and its whole arc is on record. Line the two peaks up, and Duncan's path sketches the road Finnegan is walking now.

The trade-off
- Comes with Finn already attached — a short form that needs no explaining and works from cradle to career.
- Spelled the way it sounds for English speakers, and long familiar as a surname, so most people read it correctly on sight.
- Sits in an established American pattern of Irish surnames used as first names, so it is recognizable without being interchangeable.
- Traceable in an unbroken line back to Irish fionn, giving it real depth behind a modern-sounding choice.
- Formal enough on a document and casual enough on a roster, without needing a second version.
- Finn is a great deal more common than Finnegan, so a child may end up called Finn nearly everywhere and the full name reserved for teachers and forms. Worth deciding in advance whether that suits you.
- The Finnigan spelling exists and is close enough that some people will guess wrong; expect to spell it occasionally, though rarely more than once per person.
- Joyce's Finnegans Wake has a reputation as the hardest novel in English, and literary types will mention it. It is a passing joke rather than a burden.
- It reads clearly as an Irish-heritage name. If that connection isn't part of your family's story, some people will assume it is.
