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.

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.

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.

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.

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.

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.

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.

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.

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.

With its cool -X ending, Jax is an update on the classic nickname Jack, likely inspired by the rise of Jackson.

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.

Maggie is a cute, earthy short form that has been in style for several decades now, still sometimes used as an independent name by such parents as Jon Stewart. First used in Scotland, it got a large bump in popularity via the 1971 Rod Stewart hit song "Maggie May."
