Favorites Outside of the Top 100 (Boys)

There's Rhys and there's Reese (now more popular for girls) and there's Reece, and we particularly like the traditional Welsh spelling, which entered the list in 2004, possibly influenced by Jonathan Rhys Meyers, of The Tudors, and Welsh-born actor Rhys Ifans.

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.

River shares the tranquil feeling of all the water names, and seems to have pretty much escaped its past strong association with River Phoenix and his unfortunate fate. Actor Joaquin Phoenix named his son with actress Rooney Mara after his brother River.

Now that it's no longer fashionable for girls, Robin is rising for boys again. Robin Hood, Robin Williams, Christopher Robin, and Robin the Boy Wonder are all male namesakes, after all. It reentered the US Top 1000 boys names in 2015 for the first time since 1999 and continues to bounce around the lower end of the Top 1000.

Madonna did much to polish up the image of this old-neighborhood Italian choice when she picked it for her son with British director Guy Ritchie, and several years later it was also used by Rose Byrne and Bobby Canavale for their son. It now feels much more mainstream than many celebrity baby names, sharing the quirky appeal of some other so-far-out-they're-in baby names as Bruno and Hugo.

Rhythmically appealing international spin on the stiff original.

Roman is an ancient name trending in a major way. A surprise hit name of recent years, Roman now ranks in the Top 100 not only in the US but throughout the English-speaking world, and is rising in other European countries as well.

With its gentle sounds and earthy vibes, the name Rowan feels like a fusion of different styles. A word name, a surname, and a gender-neutral name, Rowan is rustic but trendy, blending the vibes of both Owen and Oakley.

Santiago is a spirited Spanish name with great crossover potential. It's a place-name (a city in Chile), a surname, and the name of the patron saint of Spain.

A name introduced here by The Godfather: James Caan played the anything-but-saintly Santino "Sonny" Corleone, and comedian Adam Carolla used it for his son.

Solomon, a name that evokes wisdom and peace, is an Old Testament name that, along with other patriarchal classics, is finally beginning to shed its long white beard and step from the pages of the Old Testament into modern nurseries.

This gentle Scandinavian name, soft and sensitive, is being discovered in a major way by parents in the US. It's most closely identified with the nineteenth century philosopher Soren Kierkegaard, but there have been modern fictional Sorens as well, in The Matrix Reloaded and the book series Guardians of Ga'Hoole, Charlie and Lola, and Underworld.

Tristan -- known through medieval legend and Wagnerian opera -- has a slightly wistful, touching air. This, combined with the name's popular "an" ending, makes Tristan very appealing to parents seeking a more original alternative to Christian.

Romantic name used throughout Europe, though sure to lead to pronunciation problems here. Though it's never been too widely used in the US, it's quite popular in Switzerland, France, Austria, and Romania.
