True Blood may be the reason that variation Rosalyn has retained some popularity while the original Rosalind still languishes. Moderately popular in the middle of the last century, Rosalyn may deserve its revival but we still prefer the more classic Rosalind.

Gone with Richard and Rick, Ricky has been falling since the turn of the 21st century. Probably still suffering from overuse in the 1990s.

Asking for trouble. Rebel Wilson is female, but this name is truly gender neutral, though hardly neutral in any other way. Rebel is undoubtedly one of the edgiest boys' names starting with the letter R.

Attracted attention as the stepmother of Princess Diana.

Director Ridley Scott and actress Daisy Ridley made this surname-style name familiar, and with its outdoorsy meaning and rugged yet preppy sound, it could blend in with Oakley, Reid, Riley, and Ridge. Some parents might be put of by the first syllable (as in, "get rid of" or "horrid" or "riddles"), but since Scarlett (scar), Colton (cult), and Titus all rank in the Top 400, it could still work for those looking for a standout last-name first name.

Riot has all the sounds of a trendy name — the first syllable that of trendy choices like Ryder, Ryker, and Rylan, rhyming with Wyatt. But the strong negative connotations of the word, suggesting violence, turn many (but not all) parents away from Riot as a baby name. Ryatt, one step removed, is more common.

With its surname-style, literary feel, and similarity in sound to Finley, Juniper, Pippa, Riley, and Presley, Ripley is an unexpected choice that was given to more than 200 girls in each recent year. First used back in the 80s, thanks to the powerful character played by Sigourney Weaver in the Alien films, it began to be used more substantially in the 2000s, after it was chosen by actress Thandiwe Newton for her daughter.

Raul and French brother Raoul are much more appealing than flat-footed daddy Ralph. Puerto Rican actor Raul Julia, who starred in the Addams Family movies, brought fame to the name before his death in 1994.

Even less subtle than Duke or Earl, this name shot up the popularity charts in 2013, the same year young Prince George was born and the craze for all things royal (and Royal) began. Today, it's a leading boys' name on Nameberry's own popularity charts.

The "Believe It or Not" jokes will get old fast, but this surname feels fun and on-trend for both girls and boys, reminiscent of Riley, Tripp, Bridger, and Oakley.

Now that names like Cannon and Gunner, fit for comic book heroes, are rising up, Rogue may fit right in.

This ultrapopular boys' name is rapidly becoming a hot name for girls; admired for its buoyant Irish spirit.

We love this partly for purely personal reasons, since it is one of our surnames. We used it as the middle name of a son –and it can make a good first choice too. Redmond – also found as Reamann or Raemonn – is the Irish form of the Germanic name that occurs in modern English as Raymond.

Ridge may be the quintessential daytime drama name, but it's still better than most. This is one word name rising rapidly through the ranks, reentering the US Top 1000 in 2015 for the first time since 1989.

With vintage names on the rise and recent data suggesting that the US is following the UK trend of nicknames-as-given-names, Ruthie joined Goldie, Daisy, and Nellie on the US Top 1000 list in 2023.

In Japan the lotus is the Buddhist symbol of purity and perfection. In the US, Ren can also be short for Lauren or Renee, but it could be misspelt as the more popular Wren.

Though it's used for boys, most non-French people would hear it as a girls’ name. Most would be surprised to learn that Rene has always charted in the US Top 1000 for boys.

Riggs, with its suave, cowboy-cool style, is one of the hottest new names on the scene. Boy names that end with S are particularly trendy right now, with similar choices Briggs, Wells, and Jones zooming up the charts.

Naming babies after precious gems as a protection against evil spirits is an ancient Japanese tradition.
