This name of three early popes has been associated in recent years with a cocky cartoon cat ("Thufferin' thuccatash!") and the Italian Stallion hero of the Rocky and Rambo movies (who was born Michael) — and yet we think it just might be ready to move further back into the mainstream.

Leonie is a chic French and German form of a name that exists in a range of variations from Leona to Leonia to Leon to Leo to Lionel, all newly fashionable after a couple of generations in style limbo.

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!).

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.

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.

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.

Probably due to its nursery rhyme association, Jill has the perpetual air of a rosy-cheeked tot -- even though it is one of the oldest names on the roster, a medieval variation on the Roman Julia. The pairing of Jack and Jill to connote a generic boy and girl goes back at least to the fifteenth century. But can knowing Jill's history keep it from sounding like a cute mid-twentieth century invention? There may be some possibility of Jill making it back up the hill.

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.

Cornelius, the New Testament name of a third century Pope and saint, is one of those venerable Latin names on the edge of consideration, despite the corny nickname alert.

After cracking the US Top 200 in the early 2000s, fueled by Jacob's rise, this name has been losing steam in recent years. But Jakob is the top form of the name in many other countries, cultures, and languages, ranking highly in Germany, Norway, Austria, Iceland, and Slovenia. Jakub is the Polish variation.

Cultured and cultivated in an old-style, Old World way, Anton is popular across Europe. It may be associated with the classic Russian playwright Anton Chekhov and also with ballroom dancer Anton Du Beke.

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.

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

If you love both unique baby names and flower names for girls, Amaryllis might be a perfect choice for you.

Annik is a pleasing combination of unusual and familiar. As first Ann and now Anna become overused, you might want to explore its wilder variations such as this Eastern European short form.

Arda is a simple gender-neutral name with several possible origins and meanings. As a Turkish name, it's usually used for males and means scepter. There is also a river in Turkey called the Arda. The Hebrew name Arda means bronze. And Arda may also be a variation of the English Arden, the name of a magical Shakespearean forest.

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.

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.

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.

Charlott is a feminine given name that represents a variation of Charlotte, which itself derives from the French feminine form of Charles. The name ultimately comes from Germanic origins, meaning 'free man' or 'strong'. While less common than Charlotte, Charlott maintains the same sophisticated and classic appeal but with a slightly more distinctive spelling. Popular throughout Europe, particularly in Germany and Scandinavian countries, Charlott offers parents a way to honor traditional naming while incorporating a subtle twist. The name has never reached the heights of popularity that Charlotte has enjoyed, but it maintains a steady presence, appealing to those seeking a name with historical roots and elegant character.
