Difficult to Spell but Oh So Beautiful!

Rugged but gentle, Rhys is the traditional Welsh spelling of this name, which can also be anglicized as Reese or Reece. Up until 2010, Reese was the preferred spelling in the US, perhaps because parents were concerned about mispronunciation. However, Rhys has since taken over for boys and is now used twice as often as Reese.

X marks the spot in names these days, usually at the middles or ends of names, but here is one that puts it squarely up front.

Before the young Irish actress Saoirse Ronan made her mark in the films Ladybird and The Lovely Bones, few of us had heard this name, let alone known how to pronounce it. But now it is slowly way edging its way into the mainstream, particularly, of course, with parents who have Irish roots. It made its first appearance in the US Top 1000 in 2016, when it was the third-fastest-rising girls' name.

Niamh, derived from the Old Irish Niam, is an ancient Irish name that was originally a term for a goddess. In Irish myth, one who bore it was Niamh of the Golden Hair, daughter of the sea god, who falls in love with Finn's son Oisin and takes him to the Land of Promise, where they stayed for three hundred years. Niamh can be Anglicized as Neve, Nieve, or Neave.

Dashiell, though missing from many other name sources, is among the hottest new names, chosen by such celebs as Cate Blanchett and author Helen (Bridget Jones) Fielding. With its great dash and panache, Dashiell is associated with detective writer Dashiell Hammett (born Samuel, as in Sam Spade, Dashiell being his mother's maiden name). Alice Cooper was ahead of the game: He named his son Dashiell in 1985.

Aoife, pronounced EE-fa, is derived from the Irish word aoibh, meaning "beauty." Aoife was borne by several different heroines of ancient Irish legend. In one tale, she was the fiercest woman warrior in the world and enemy of her twin sister, Scathach.

Anais is an unusual, alluring name forever attached to the daring French-born American novelist and diarist Anais Nin (born Angela, with Anais as one of her middle names), who became the inspiration for the naming of the daughter of musician Noel Gallagher. Anais is also the name of a popular perfume.

A pretty name that may pose pronunciation problems for non-French speakers or those who've never encountered it, but it is worth the effort. Pronounced meer-AY (or closer to MEE-RAY in French), it comes from the Occitan word mirar meaning "to admire".

A handsome Irish name for boys, very popular in that country, but in the US this traditional spelling might cause pronunciation problems. Still, whether Cian or Kian, it's simple and straightforward enough for the initiated. Cian is rising in the British popularity charts.

Actor Joaquin Phoenix (brother of River, Rain, Liberty and Summer) highlighted this one, then Kelly Ripa began talking about younger son Joaquin on her daily TV show, and presto—it's now one of the hottest and most appealing multicultural baby boy names.

Caoimhe, pronounced (more properly) kwee-va or kee-va, is a pretty and distinctive Gaelic name but one that could well lead to no end of confusion outside the Irish community. Even in its native habitat, it is sometimes spelled Keeva.

Oisin is one of the most popular Irish baby names in its native land, though largely unknown in the US. The original Oisin was the mythological son of Finn McCool and Sadb, the goddess who was changed into a deer. A legendary war hero and poet, Oisin had a name that is also reminiscent in sound of the ocean. Pronounced correctly, this name has an attractive sheen.

Long popular in Scotland, this attractive name is strictly-speaking the Gaelic version of Eleanor, but is also often considered part of the Helen family of names. After the Normans introduced it into the British Isles, it was transformed into Aileen or Evelyn. It has rarely been heard in the US, but it is slowly starting to be used here too.

Yes, it's pronounced with a long o sound at the end, just like Margo and Margot. This spelling was popularized by supermodel, actress, and tragic Hemingway granddaughter Margaux, whose name spelling came courtesy of a bottle of French wine. (The original spelling of her name was Margot; she changed it when she heard her parents were drinking a bottle of Chateau Margaux the night she was conceived.) Margo itself is a diminutive of Margaret, which means "pearl" or, in its French version, "daisy." Margaret or Marguerite would be more stylish variations now.

Siobhan is the Irish variation of Joan, which is derived from the ancient Anglo-Norman name Jehanne. In this way Siobhan is indirectly related to the name Sinead—the Irish form of Jeannette, which also derived from Jehanne—although Sinead is not a nickname for Siobhan. Siobhan was the name of several early Irish queens and was introduced to the American public by the actress Siobhan McKenna.

The gorgeous and romantic name Xiomara popped into the Top 1000 from 2004-2011 after a contestant on America's Next Top Model increased interest in her rare name.

Aisling is currently a very popular Irish name for girls. Pronounced variously as ASH-ling, ASH-lin or ash-LEEN, it was part of the revival of authentic Irish names in the twentieth century, and is now being sparingly used by U.S. parents in place of the dated Ashley--though often spelled phonetically as Ashlyn or Ashlynn.

No, the pronunciation--ro-SHEEN--isn't immediately obvious to the non-Gaelic viewer, but the sound of this shiny Irish version of Rose is pretty enough to make it worth considering. Very popular in its native Ireland, it's one of many Irish girl names finding a wider audience. Earlier generations Anglicized at as Rosaleen, but we stay stick to the original.

Xochitl is a Nahuatl or Aztec floral name used in southern Mexico and pronounced SO-chee-tl or SHO-chee-tl, although sometimes the "tl" at the end is not pronounced. Internet entrepreneur Xochi Birch is probably the best-known bearer in the US – except for the Xochitl brand tortilla chips. Definitely among the most intriguing international flower names and a beautiful choice for those looking to honor Nahuatl heritage.

More commonly seen here as Anya, this traditional yet unique Irish name belonged to the queen of the Munster fairies and is sprinkled throughout Irish folklore as an early Celtic goddess of summer and prosperity. One of the most popular baby names in Ireland, Aine's spelling and pronunciation might seem simple but could prove confusing in the U.S.
