This Irish name of a saint from the Isle of Aran also appears in myth and fantasy fiction, giving it an intriguing, mystical air.

Virtually unknown in this country, Donnacha is currently in the Top 100 in Ireland. According to legend, Donnacha was a High King of Ireland until his death in 1064. The English version Donaga (done-a) might be preferable here.

The name of an ancient Irish saint is in the contemporary Irish Top 50. While it's one of the rare Irish names for boys that hasn't immigrated to the U.S., it may follow brothers Aidan and Declan to our shores. The t is not pronounced.

Much stronger than Dale for a boy.

This is an ancient saints' name well used in Ireland but a rarity here and unlikely to ever reach the popularity of other Finn-ish names. St. Finbarr (the more common spelling) is the patron saint of Cork and in Irish folklore, Finbarr was king of the fairies.

Fionn, the modern Irish form of Finn, is more popular in Ireland these days than Finn, which is rising fast in the U.S. where Fionn is virtually unknown. That's probably a good thing, because few Americans would know that Fionn and Finn have the same root and are pronounced the same, like the fin of a fish. It's the namesake of a great hero from Irish mythology, Fionn MacCumhaill, who acquired divine wisdom by eating an enchanted salmon of knowledge.

Odhran, Anglicized as Oran, was the name of an ancient saint. Today, Odhran is among the Top 100 Irish names for boys in Ireland.

Egan's likeness to the word eager gives this Irish surname a ready-to-please, effervescent energy, and it would make an appropriate substitute for the overused Aidan.

Cahir along with its traditional spelling Cathair is well-used in modern Ireland. Now it's finding a wider audience thanks to The Witcher , though Cahir is the main villain of the series. It was in the US charts from 2017 to 2020, but fewer than 5 baby boys were named Cahir in the US in 2021, suggesting that the effect on parents was short-lived.

Brogan is a cheerful Irish surname that would fit right in with the Logans and Br-starting names now trendy for boys. It's been on the pop list for the past three years, though it's sliding again. Its history includes Saint Brogan (Broccan in Gaelic), who was Saint Patrick's nephew and scribe.

Tiernan is the slightly edgier and sharper cousin of Kiernan. This is one Irish surname that is attractive but distinctive; Tierney is another, related, option.

An Irish surname possibility for those who like Daley, Royal, Dougal, and Dolan, though it may sound too much like doily to catch on for modern boys. Nevertheless, it was fairly well used in the 20th century, popular in the 30s, 40s, and 50s when it reached the Top 200 at one point.

With the current taste for last names first, this sounds a lot cooler than Shawn; it also has creative connections to the great Irish playwright, George Bernard Shaw, novelist Irwin Shaw, and Big Band Era clarinetist/bandleader and one-time Ava Gardner husband Artie Shaw.

Made famous by F. Scott Fitzgerald and John Fitzgerald Kennedy; still works best as a middle name.

Now that the Irish Ciaran and Ciara -- aka Kieran and Kiera -- are becoming more popular beyond their native shores, the short and strong Ciar might find some favor. As of now, more than 160 baby girls were named Ciara in the US last year, with half that many boys named Ciaran, but so far no baby boys named Ciar, though 17 were called Keir.

Dermot is an appealing, relatively undiscovered Irish mythological hero's name long popular in the Old Country, and imported into the American consciousness by actor Dermot Mulroney. We see it in the next Celtic wave following Connor and Liam.

Sheridan is one surname-name that hasn't come into style for either gender, though it was lightly used for boys around the turn of the 20th century and girls 100 years later. The name does have an attractive sound and an appealing meaning.

Cheerful but laidback, surname-style Delaney is derived from the Old Irish name Dubhshláine and has become a familiar choice for girls in recent decades. Nevertheless, it has also been used for boys since the early 1900s and was equally - though rarely - given to both, right up until the 1990s.

The name of a 6th saint from Galway whose monastery became a center of learning while he was there, Iarlaith is an undiscovered Irish gem. Undiscovered in the US, that is: Iarlaith is a Top 100 name in Ireland, given to around 55 boys in a recent year.

A beaming, friendly Irish last-name-first-name waiting to be discovered, though anyone into American history might associate it with John C. Calhoun, a 19th century statesman who defended slavery. There are however plenty of places called Calhoun which might lessen that association.
