If You Like The Name Liam, Here Are 20 More Baby Names From The British Isles

Originally a pet name for the Irish moniker Aodh, the Celtic god of Fire, Aiden means "little and fiery," according to Nameberry: Aiden is a variation of Aidan, the anglicized version of the Irish Aodhán, "originally a pet form of the Irish name Aodh (pronounced 'ee'), who was the old Celtic god of the sun and fire."

If you're looking for a Celtic name that is accessible but distinctive like Liam, Brennan is a great choice that will set your little one just a bit apart from the rest. Don't let the meaning get you down ("descendent of the sad one," per Nameberry).

Irish for "dove," Colm is a gentle name for a boy you'd hope to impart his peaceful nature wherever he goes. But it's not pronounced like "calm," even if the meaning is a peaceful one: "Pronunciation is two syllables instead of one, like Colin with an 'm' at the end," explained Nameberry.

Talk about powerful. Conall means "strong as a wolf" and is a great alternative to all the little Connors your son will be running around with. And it can be spelled with one "l" or two, depending on your preference.

Cormac is a cheerful, rough-and-tumble choice that means "charioteer" and has a few illustrious members of its club, including author Cormac McCarthy and Cormac McLaggen, a classmate and fellow Gryffindor in J.K. Rowling's Harry Potter series. And Cormac is pretty compact already, but you can always shorten this name to "Mac" in a pinch.

Wouldn't having a little Finn be adorable? Irish for "fair," Finnegan is a playful yet resolute choice, especially for parents who love literature; the title of Finnegans Wake by James Joyce came from an old Irish-American song.

Playful and melodic, Finnian is a variant of the above Finnegan and also offers Finn and Ian as pet names. You might be familiar with its alternate spelling Finian thanks to the the classic 1968 Broadway musical Finian's Rainbow, later made into a film starring Fred Astaire as Finian McLonergan.

Looking for a name fit for a warrior? Garrett is a strong choice that means "spear strength" in Irish and has several spellings to make it even more interesting. "Gareth" is another, similar option with a slightly softer feel.

A name fit for a king, Niall (pronounced nye-all) recalls the royal Irish ancestor that spawned all the O'Neills and MacNeils that have followed. Maybe this would be a good choice for someone whose surname won't be passed to their son.

Attractive and distinctive, Tiernan has lent its authority to a whole spate of Celtic kings and saints over the centuries. It's perennially popular in Northern Ireland, perhaps due to meaning "little lord." (You've probably had a pint or two at a pub named Tiernan's at some point or another, as well.)

If you love the ethereal beauty of Guinevere but are afraid you won't be doing your baby girl any favors with such a long and storied moniker, cut it short with the cute Gwen. Meaning "white circle," this Welsh name will bestow the same glowing beauty as the former without twisting little tongues.

Scottish for "white and fair," Fiona is a lilting little beauty for your baby girl. And while it's not super popular, it's still familiar enough thanks to pop culture references like Princess Fiona from Shrek, Fiona Apple and the Fiona character from Shameless.

For something that's botanical but not full-out floral, Bryony is the name of a climbing vine that the Brits love to bestow on little sprouting girls. It's not a name you hear particularly often in the U.S., but it is lovely and romantic and poised for popularity, don't you think?

Derived from the German language meaning "battle-ready," this name was introduced into the English language in the 11th century by the Flemish queen of William the Conquerer and has enjoyed a storied tenure in the culture ever since. "Waltzing Matilda," anyone?

A very popular choice in Britain that never made the jump across the pond, Nicola means "people of victory" and is a more distinctive choice than Nicole. Elegant and charming, it's the name that brings castles and unicorns to mind.

Like Nicola above, Philippa has been a British standard forever and counts royal sister-in-law Philippa Middleton and Geoffrey Chaucer's wife Phillipa Roet among its members.

Exorted by Shakespeare to be "blithe and bonny" in A Midsummer's Night Dream, girls with this name will undoubtedly be as happy and carefree as Blythe compels them to be.

Dainty and sweet, Cecily has graced several namesakes in history like the mother of King Richard III, who was known as "the rose of Raby," the Beatrix Potter bunny Cecily Parsley, and actress Cecily Tyson.

Related to the rocky Scottish island Ailsa Craig, Nameberry suggests Ailsa might be a nice alternative to Ashley or Elsa. It means "elf victory" and would be perfect for your little pixie.

With a long literary history that includes Shakespeare, Dante, and ahem, Tarantino, "she who brings happiness" is sure to brighten your life upon her arrival. And think of all the nicknames!

In Welsh mythology, Bronwen was daughter to the god of the sea and has been the namesake of little girls throughout the country's history. It's dignified, a touch exotic, and you can have a cute little Winnie running around in a crowd of Emmas.
