To all the names I've loved before

Jack may have fallen from its Number 1 place in England, but in the US it's as popular as it was at its height in the 1920s and 1930s. A durable, cheery, everyman form of John, Jack ranks as one of the most popular boy names starting with J.

As a precious stone, Jade is known for its cool green hues, its importance in Chinese art, and its ability to transmit wisdom, confidence, and clarity. As a name however, Jade is a 90’s throwback in the UK, a Number 1 choice in France, and a returning gem in the US right now.

James is one of the classic Anglo-Saxon names, a stalwart through the ages that is more popular—and yes, stylish—than ever today. It recently came out Number 1 in a poll of America's favorite boys' baby names, and is the most common male name, counting people of all ages, in the US.

No, we don't consider Jane too plain. In fact, for a venerable and short one-syllable name, we think it packs a surprising amount of punch, as compared to the related Jean and Joan.

Pronounced just like Jean in the English-speaking world, but as the more unusual zhahn in France, this has sailed away with the first wave of French favorites: Denise, Michelle, et soeurs.

Josephine, with its large measure of class and character and a gently offbeat quality, has been on a gentle uphill climb in the US for over 30 years, now ranking in the Top 100. With an intriguing number of vivacious nicknames, from Jo to Josie to Fifi to Posy, Josephine is a Nameberry favorite.

Julia was an ancient Roman imperial name given to females in the house of a Julius, as in Caesar. Its origin is shrouded in history, but possible roots include Latin iuvenis, meaning "youthfu"; Greek ioulos, meaning "downy-bearded"; or Jovis, a form of Jupiter, which means "sky father".

A Top 100 name from 1896 to 1921, Leona reached as high as Number 72. Since then, Leona had seemed to be one of the most unfashionable of the pride of lion names, but singer Leona Lewis has done a lot to rejuvenate it. Leona returned to the Top 1000 in 2009 after decades of being away.

Its mellifluous sound makes Leonora--which has a rich history and a tie to the popular Leo names-- a keen possibility for revival. Though it's been hiding below the Top 1000 since the 1940s, Leonora is being rediscovered by stylish parents in the US and Europe.

Lily is the most popular of the popular delicate century-old flower names now making a return, thanks to its many irresistible attributes: a cool elegance and a lovely sound, a symbol of purity and innocence, and a role in Christian imagery.

Kate and William shocked the world when they announced that they'd named their third child Louis -- Prince Louis Arthur Charles, to be more precise. But we've been predicting a comeback for this classic name for a long time.

Louise has for several decades now been seen as competent, studious, and efficient—desirable if not dramatic qualities. But now along with a raft of other L names, as well as cousin Eloise, Louise is up for reappreciation—sleek and chic, stylish in Paris, and starting to become so in the US as well. Louisa is perhaps more in tune with the times, but Louise has more edge. Louise has been on the rise lately, and reentered the US Top 1000 for the first time in a quarter century in 2016.

The related Lucas and Luke are both hugely popular boy names in the US and internationally, and now Luca has joined them on boys' popularity lists around the world.

Lucas is a Top 10 boys' name with a slightly-less-popular almost-identical twin brother, Luke. Like Elijah and Elias, Lucas and Luke come from the same root and have the same meaning and so feel even more popular than they are.

A versatile classic, Lucy is both sweet and solid, a saint's name, and the heroine of several great novels. First fashionable in England and Wales, Lucy is now a popular choice in the US, The Netherlands, and New Zealand.

French spelling of Leo, currently a bit hit with French-speaking parents.

This name, which is a French variant of Leo, is pronounced with the distinct French nasally N at the end. It is sometimes used in French to refer to popes named Leo.

Leona with a French accent that gives it a bit more flair. It's currently very popular there – in the Top 30 for French baby girls.

Cross-cultural winner.
