The long history and solid usage of Henry has infiltrated other cultures, where a number of variations experience the same degree of popularity. In the US, Henrik first entered the Top 1000 in 2014. In Norway, Henrik is a mega popular choice.

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.

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.

This nickname-name is very popular in Germany, though Lottie is still the preferred version in the US. The problem, of course, is that you'll have to put up with a lotta jokes. See?

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.

Leja is a feminine name with Slavic origins, particularly common in Slovenia and other Eastern European countries. The name may be derived from the Slavic word 'leja' meaning 'woodland' or 'forest glade.' In some contexts, it can also be related to the word for 'pouring' or 'flowing.' Leja has a delicate, melodic quality that contributes to its appeal. While not widely used internationally, it remains a cherished traditional name in its regions of origin. The name carries connotations of natural beauty and serenity, evoking images of peaceful forest clearings. Its simplicity and distinctive sound make it both memorable and elegant as a given name for girls.

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.

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".

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.

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.

Well used throughout The Netherlands, Germany, Norway, and Denmark, Lasse is a variation of Laurence, typically used as a nickname for the related Lars. While English speakers may be tempted to say "lass" or "lassie", the correct pronunciation would LA-suh in Denmark, LAHS-seh in Norway and Finland, and LA-seh in Sweden and Germany.

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.

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.

Ceris is a feminine name with Welsh origins, often associated with the cherry tree or cherry fruit. This concise, two-syllable name (pronounced either as KEH-ris or SEH-ris) carries natural symbolism and beauty. In Welsh tradition, Ceris connects to sweetness, fertility, and the renewal of spring. Though relatively uncommon even in Wales, it represents a distinctive alternative to more popular nature-inspired names. Ceris has remained somewhat under the radar internationally but appeals to parents seeking a name with Celtic heritage that's both recognizable and unique. Its brevity and soft sound give it a contemporary feel despite its traditional roots. The name's connection to cherries also links it to qualities of sweetness, vitality, and natural beauty.

Loki is the shape-shifting, gender-bending god of mischief in Norse mythology. Taking several animal forms, from a salmon to a seal to a fly, Loki is alternately friend and foe of the gods.

The addition of the h makes it more Old World, which is not the direction you want to push Matilda in.

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

Catharina is a feminine name with deep European roots, particularly common in Germanic, Scandinavian, and Dutch-speaking regions. It derives from the Greek name Aikaterine, later Latinized to Catharina, meaning 'pure.' This elegant, classical variation of Catherine carries a regal quality, having been borne by numerous European queens and noblewomen throughout history. While Catherine and Katherine are more common in English-speaking countries, Catharina maintains popularity in continental Europe. The name offers a formal, sophisticated alternative with international appeal. Its rich historical connections and melodious pronunciation give it an air of timeless elegance. Though less common in contemporary America and Britain, Catharina represents a distinguished heritage choice with cross-cultural versatility.

One of the many names with a strong "er" sound, like Bertram and Ernest, that was huge in the 1920s and is languishing in style limbo now. One famous bearer is the physicist Erwin Schrödinger, as in Schrödinger's cat.
