Bubbly, bright, and versatile, Phoebe is a name with mythological, biblical, and literary ties. Used since the 17th century, it fell out of fashion in the US during the '60s, only to be revived after it appeared in the 90's TV favorite, Friends.

Riley—an upbeat, friendly surname name—is red hot for girls and still going strong for boys. If you haven't been spending much time around babies recently, you may be surprised to learn that Riley is the most popular girls' name starting with R and also the Number 1 Irish name for girls in the US.

Oscar is one of the most stylish Old Man Names of our era. While it's softened slightly in popularity over the past 20 years, that may be considered a very good thing.

Leo is a strong-yet-friendly name that was common among the Romans, used for fourteen popes, and is now at its highest point ever in the US thanks in part to Leonardo "Leo" DiCaprio.

Elsie is a sweet vintage nickname-name turned modern star. After a 30-year hiatus, Elsie started climbing the US popularity list 20 years ago and is still headed for the top.

This spirited Gaelic classic, which became popular in Ireland via the illustrious twelfth century king Rory O'Connor, makes a highly energetic choice, now used for either sex. Rory's gender split is still trending boyward; it's one of the coolest boys' names starting with R.

Millie is back. It's a popular name throughout much of the English-speaking world, and broke the US Top 100 in 2024. Millicent would be an appealing long form, but many people are using Millie all by its cute self.

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

Lula has a firecracker personality, a singing and dancing extrovert. Interesting that Lulu was a Top 100 name when the Social Security list was born in 1880, but it's been sliding ever since and has not been in the Top 1000 for decades. Modern parents in love with Lulu might well reverse that trend.

This pet form of such names as Winifred and Edwina and Gwendolyn has loads of vintage charm, a la Millie and Maisie, with a decidedly winning vibe. And it just got celebrity cred as the baby daughter of Jimmy Fallon.

Archie made global news as the surprise first name of the newborn royal baby, son of the Duke and Duchess of Sussex aka Harry and Meghan. Archie has now officially transcended Archie Bunker and Riverdale's Archie to take the, um, throne as the quintessential retro nickname name.

Ellie first took off in the UK—yes, in this nickname form—and this warm and friendly name has also become hugely popular here. In 2011, Ellie entered the US Top 100 girl names for the first time and has remained near the top of the charts ever since.

A favorite in England and Wales where nicknames as given names are very much the norm, Tilly has the potential to catch on in the US, given its similarity to the popular Lily and Ellie and the rising stars Millie, Billie, Kallie, and Nellie.

Lottie is a nostalgic great-grandma name that conjures up lockets and lace, and — like Nellie, Josie, Hattie, Tillie, and Milly — has considerable vintage charm.

Chosen for their daughter by Bruce and Demi (inspired by the To Kill a Mockingbirdcharacter), and for her son by Tai Babilonia, an interesting choice for either sex, with overtones of a "good scout" and the upstanding qualities of a Boy/Girl Scout.

Riley -- one of the most popular unisex names -- is trendier now for girls though for boys it's a classic, ALWAYS ranking in the US Top 1000.

Holly ranks just in British Top 50, but it's been out of favor here since the 1970s Era of Nickname Names. Still, the name may be on her way back as a rejuvenated nature pick.

Bobby is the quintessential mid-century nickname, the name of the son on Mad Men and overused to the point of cliche. Though Robert is still a highly popular choice, most Roberts today are called by their full name or Rob or Robbie rather than Bob or Bobby.

An alternative to the no-longer-fresh Molly, the initial 'P' gives Polly a peppier sound, combining the cozy virtues of an old-timey name with the bounce of a barmaid.

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.
