Bonnie is an adorable nickname name, heading back up the popularity list after a 50-year nap. A Top 100 girls' name throughout the rest of the English-speaking world, Americans are later to jump on the Bonnie bandwagon but now it's trending here too.

Since this was the name chosen by the late Roman Catholic pope in 2013, Francis has come into the spotlight.

Celia, splendidly sleek and feminine, is a name that was scattered throughout Shakespeare and other Elizabethan literature, but still manages to feel totally modern. Derived from the Latin Caelius, it means "heavenly".

Now that many dogs are named Max, it's safe to use this sleek, solid, regal name again for your child. And with the charm of its final x, its regal meaning, and its offbeat simplicity, Rex is definitely one to consider.

Pearl, like Ruby, has begun to be polished up for a new generation of fashionable children after a century of jewelry box storage. The birthstone for the month of June, Pearl could also make a fresher middle name alternative to the overused Rose. Cool couple Maya Rudolph and Paul Thomas Anderson named their daughter Pearl Minnie, followed by Jack Osbourne picking Pearl Clementine. Several celebs have put it in the middle spot, as in Busy Philipps's Cricket Pearl, Jake Owen's Olive Pearl and Caleb Followill's Dixie Pearl .

Nash is an English surname whose sound puts it right in step with currently trendy names like Cash, Dash and Ash. It first came to prominence via TV character Nash Bridges, portrayed by Don Johnson in the late nineties, and also via mathematician John Nash, played by Russell Crowe in the acclaimed film A Beautiful Mind.

Just as Seamus/Seumus is Irish for James, Hamish is the Scottish form — one that's not often used here, but still redolent of Olde Scotland. If you're ready to go further than Duncan and Malcolm, out to Laird and Ewan territory, this may be worth consideration. It also sounds just like the Yiddish word for homey.

Lewis is the best spelling to choose if you want this pronounced with the S. It was a Top 100 name in the US from 1880 to 1930, reaching Number 30 in 1880 and while it has declined in use, it has remained in the Top 1000 since stats began.

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.

To some, Nancy is a sweet, sparkly, vintage choice with plenty of energy and style. For it strays too much into '"old-lady" territory to be cool again yet. It's out of fashion in France, New Zealand, and Canada; it lingers towards to bottom of the US charts. In the UK however, Nancy has been a Top 100 name for nearly a decade where it fits right in with Evie, Mabel, and Pippa.

Lucius is an old Roman clan name that has lots of religious and literary resonance, yet is still vital today. It was the name of three popes, appears in several Shakespeare plays, and, like all the names beginning with 'luc' relates to the Latin word for light.It was one of a limited number of forenames used in ancient Rome, and because of its meaning was often given to boys born at dawn.

Could Hal be the Jack, Max, or Gus of the future? It just might happen in the new nickname environment, especially with Cal and Cy feeling cool, and with the interest in vintage, cowboy-esque choices, considering Hal ranked in the US Top 1000 in the first half of the 20th century.

One of the most popular Spanish names for boys in the US, Javier is embodied for many Americans in the magnetic persona of Spanish-born Oscar-nominated actor Javier Bardem.

Dorothea is a romantic Victorian-sounding name that blends elegance, gravitas and a hint of clunkiness too. Popular in the early decades of the twentieth century, it has been off the charts since 1970, however it's definitely on the brink of a revival! In fact, it has already been making its way back into the UK Top 1000, and a recent year saw it given to 90 girls in the US — three times the number it was given to a decade prior.

Mack, when "formalized" with the final k, makes an engagingly amiable choice, a far more uncommon alternative to the ubiquitous Max and Jack, with a nice, every-guy feel. Mack entered the popularity list in 2009 for the first time since 1989 and continues to climb. However, it's still far from its peak — it was a Top 100 name in 1900.

Brynn outshines the original Welsh Bryn in the popularity stakes. This simple, brisk name might be seen as a combination of Bree and Lynn, an androgynous-sounding choice that especially in this spelling is not truly unisex: Brynn, for boys, is not even in the Top 1000.

When Harrison is too much, but Harry isn't enough, try this stylish surname name with a touch of British flair. It briefly reentered the US Top 1000 for the first time since 1988 in 2016, but has since dropped just below the radar again.

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.

Sweet and cosy with a touch of sass, this nickname-y choice was a familiar option up until the sixties in the US.
