This feminine diminutive of John from the Isle of Man is also sometimes used as a variant of Judith. Still, we think it is as attractive as Thomasina or Jacoba -- that is, not very.

Kerensa, forever romantic, is a rare Cornish name spelled with an 's' or 'z', the most modern of the Karen family. Kerensa (or Kerenza) has ties to the Welsh Cerys.

This name is unusual enough that the spelling variation won't be too much of a further complication. While the Biblical cognate Cain may be more classic, this removes the name from any negative associations.

Killian – aka Cillian – is a spirited yet resonant Gaelic name that was borne by several Irish saints and could make a distinctive replacement for the dated Kelly. Kylian is another spelling that's gaining traction, thanks to French soccer star Kylian Mbappé. Possible downsides: an unsavory first syllable and a connection to the trendy brew.

Llyr is a name with a great meaning and a lovely sound, but that sound is going to be next to impossible to get non-Welsh speaking people to pronounce (google the double L sound in Welsh). If you are outside Wales, you may wish to consider the Irish alternative Lir, which has the same meaning and an easier sound.

Lorcan is a name rich in Irish history as belonging to several kings, including the grandfather of the most famous high king of Ireland, Brian Boru. Lorcan O'Toole, known in English as Laurence O'Toole, is the patron saint of Dublin, so it's not too surprising that Irish-born actor Peter O'Toole named his son Lorcan.

Could Lowen be the next Owen? This Cornish name certainly has the right sounds to be an American hit, and is rising dramatically for both boys and girls.

A jovial and jaunty Irish name, the title of a long-gone TV crime drama, this would make an appealing choice. Slight downside: Maddy is already a mega-popular nickname for Madeline/Madelyn and Madison, so this Mad- name might not feel as distinctive as the stats would suggest.

Pronounced MAW-rayt or ma-REYD, Mairead is close enough to Maureen to be accepted here. The name became popular in Ireland due to admiration for the saint of that name. Peig and Peigi are its Irish-language nicknames.

Morgan, once split evenly between the sexes, is a strong and attractive Welsh favorite, still a common boys’ name in Wales. Morgan is now more often a girls' name in the U.S. – about 2000 girls were given the name in one recent year, vs. 362 boys – though it's one of the most traditional unisex choices. Morgan was actually a Top 200 pick for boys in Victorian Britain!

This surname name popularized for girls by TV's Murphy Brown back in the 80's and 90's still has some breezy energy. Almost 400 baby girls were named Murphy in 2021, versus just over 200 baby boys, making the name solidly gender neutral.

This jaunty Celtic surname -- the most common family name in both Ireland and the US -- is totally viable as a first. The arguably most famous Murphy is TV's Murphy Brown, and indeed the name is twice as common for baby girls as for baby boys today. But still, it's solidly gender neutral and works equally well for all sexes.

Intriguing Old Welsh name being revived there, but would have major pronunciation problems here.

Nimue (Lady of the Lake) is the ruler of Avalon in the Arthurian legend. Nimue plays a pivotal role in many stories, including giving King Arthur his sword Excalibur, enchanting Merlin, and raising Lancelot after the death of his father.

The friendly and sporty feeling Nolan blends some of the best qualities of other popular boy names. With the gentle but energetic sounds of Noah, a hint of the classic Nicholas, and the cool, surname-style vibe of Greyson or Colton, it makes for a familiar and grounded choice.

Nolwenn is popular in Wales but would be a very adventurous choice in the US. Though with the increased visibility of names like Arwen, thanks to Lord of the Rings, it may not feel as odd going forward as it might have a generation ago. Other, similar ideas: Olwen, Anwen, Bronwen, Rowena.

The name of the son of the legendary Finn McCool is often Anglicized to Ossian, but the original has recently been revived in Ireland and is currently among the most popular boys' names there.
