EOWAYNE-BOYS

Still very Old European, conjuring up the image of a classical composer. But surprisingly, it's now been in the Top 600 in the U.S. since the turn of the 21st century, largely thanks to Heidi Klum and Seal's young son.

An Old World name that might have a chance to rise again with other ancient and worldly forms. Be sure to say yo-HAHN-es.

Joseph is one of the most classic names in American nomenclature, popular with parents from many ethnic backgrounds and having dual-religious appeal.

Jude is a modern star, maintaining a steady level of popularity -- but not TOO much popularity -- for more than a decade now. Thank Jude Law and the great Lennon-McCartney song "Hey Jude", double-handedly responsible for propelling Jude up the charts.

Cool and charming, with plenty of flair and sophistication, Julian manages to strike the balance between being a sensible classic and contemporary choice. Appealingly international, it is no wonder Julian is a rising star.

Variant of Caelan

Kai is an internationally flexible name with many possible origins and meanings, growing in popularity in the US and a diverse range of European countries.

While Keegan has been rising in popularity for a number of years, this variant spelling has dropped in the lists.

Keegan is one of a clan of spirited Irish surnames starting with K and ending with 'n'--this one with the cheery double 'e' in the middle-- that are appealing to an increasing number of parents. It derives from Mac Aodhagáin, meaning "son (or descendant) of Aodhagán," a diminutive of the Irish name Aodh--pronounced Aye.

Kellen is German in origin and Irish in spirit. Kellen has fallen a bit in popularity for boys since its peak in 2012, but it has possibilities for girls too. In fact, Kellen's similarity to such feminine names as Helen, Ellen, and Kelly makes it feel more unisex or even female, though Twilight actor Kellan Lutz has done much to popularize this name for boys.

Kelsey (ex-Frasier) Grammer is a famous male bearer, although most modern Kelseys are female. It derives from several English place names, possibly meaning "Cenel's island", from the Old English name Cenel "fierce".

This attractive surname name still projects that Kennedy family charisma. While it didn't come into widespread use until long after the deaths of martyred heroes President John F. or Senator Robert Kennedy, Kennedy is now one of the most popular unisex names, particularly for girls. This is one name that manages to sound trendy and traditional at the same time.

Sharp attractive short form which has a nautical translation in German: "keel" (although it isn't used as a name there).

Although this surname name is closely related to the more common Irish name Kieran, Kiernan is also a well used family name, tied to thirty-three ancient chieftains. It has on a few occasions been used for girls.

Chosen for their first son by musical couple Gwen Stefani and Gavin Rossdale, this Jamaican place and elegant British surname also boasts the more regal yet user-friendly short form, King.

Attractive attenuated form of the popular Christopher, well used throughout Europe, appearing as Christophe in France and Christoph in Germany.

A name that defines itself, a bit more curt in the harder K version.

Lachlan is as Scottish as haggis and tartan plaid kilts—a favorite used throughout England, Scotland, Australia, and New Zealand—and just beginning to be noticed in the US: it reached the Top 1000 for the first time in 2013. An ancient name, Lachlan was originally used to describe the Viking invaders of Scotland, those from the land of the lochs.

British place-name unlikely to evoke much passion in any baby namer.
