There's something particularly attractive about names with an interior "j" and Arjan is a prime example. The Punjabi version is pronounced with a conventional j as in jar; the Dutch Arjan, which is a variation of Adrien, pronounces the 'j' like a 'y', while the Albanian pronunciation has three syllables and is a variant of Arian. A multicultural choice, Arjan is in the Top 1000 in England and Wales.

Mathilde is even more popular in France than Matilda, a hipster favorite thanks to Michelle Williams and Heath Ledger, is here. And the French pronunciation, while confusing to English speakers, makes it softer and prettier than the version we're more familiar with. It's also very popular in Denmark and Noway, pronounced closer to the English variant.

Gray-bearded name heard primarily in Sweden and Germany.

Both Karla and Carla are sliding down the ranks, though Karla remains far more popular in the USA than Carla.

Traditional German names of this ilk have had a difficult time emigrating into the American name pool, mostly because anti-German sentiment during the two world wars of the 20th century drove German names out of fashion. One of Heinrich's nicknames, Harro, might do better.

Ferdinand is a traditional name among Spanish royal families and also appears in Shakespeare's The Tempest, borne by the handsome young prince shipwrecked on Prospero's island. Bold, daring, and poetic, it was a popular choice in the US in the 19th and early 20th century, but the 1938 movie Ferdinand the Bull has left it with a lingering clunkiness and it has been out of style since the 80s.

Short for Brunhilda, the operatic Valkyrie of Teutonic legend, Hilda still has not quite shaken off that image that image. Though with the resurgence of Matilda, she might just have a bit of a comeback.

This name's popularity peaked in the 1930s in the mid 600s - but we think it is time for a reconsideration. Arvin feels more modern than similar names like Marvin and Alvin. It also boasts a beautiful meaning and defies easy shortening (which is an asset to many parents who choose a name because they want it to be used!).

A sleek, smooth, understated name off the grid in the US but among the Top 100 girl names in Germany. In the US, it is a unisex name, while in Germany and the Netherlands, it is predominantly feminine.

Lisbeth is one of the many short forms of Elizabeth that are used on their own. Not only is it the name of the mother of the main character in George Eliot's novel Adam Bede, but it takes on a whole new, powerful image as the heroine of The Girl With the Dragon Tattoo trilogy. Lizbeth is another spelling.

More likely to be spelled Constantine, this was the name of the first Christian emperor of the Roman empire, as well as three Scottish kings. Previously thought of as too bulky and unwieldy a name for a modern child, these days it would be perfectly acceptable.

Sounds like exactly what it is: The name of a romance novel hero.

Laurie morphed into the more streamlined Lori in the sixties but now feels dated for a girl in either spelling. Update Lauren has been renovated as Laurel or Laura itself.

Although often connected to the men's magazine title, Maxim is a chic and powerful name for a little boy. It's proving moderately popular too, having been in the Top 1000 in the US since the year 2000.

This cognate of Jerome (of all things), familiar via the Dutch painter of fantastical scenes, H. Bosch, would appeal only to the most audacious, intrepid, attention-seeking baby namer. It is, however, still used in Germany, especially in Catholic Bavaria and in the north German Rhineland.

Simple but substantial, Lani is surprisingly underused considering the popularity of Lainey, Leilani, Lana, and Kehlani. A multi-cultural choice with both Hawaiian and English origins, it is also used in the Philippines, possibly as a variation of the modern Laarni, or as a twist on the word langit meaning "skies, heaven", which aligns with the Hawaiian meaning too.

Mads is a perennial favorite in Germany, the Nordic countries, and the Netherlands, where it is usually to be found in the Top 50. Just remember the D is not pronounced. Famous bearers include Danish actor Mads Mikkelsen, the villain of the Bond film "Casino Royale".

The unusual-to-the-English-ear Moritz is a Top 25 name in Austria and a form of Maurice or Morris, which are modern variations of the ancient Roman Maurus. There were several early saints named Maurus and a famous 3rd century Saint Maurice, who was a Roman infantryman who was martyred when he refused to worship Roman gods. The Moritz form also references the posh Swiss ski resort St. Moritz and Justine Moritz is a character from Mary Shelley's novel, Frankenstein.

This traditional Germanic name hasn't been on the U.S. list since 1958, but perhaps due to the mythic power of painter Frida Kahlo, parents are beginning to show some interest in it.

This jazzy old name could make a comeback, the way Josephine and Ella have. In England the name was popularized by Queen Victoria's daughter Princess Louise Caroline Alberta, after whom her governor general of Canada husband named the North American province. Jazz singer Alberta Hunter was a noted bearer.
