Baby Girl

Strong and solid, with a touch of foreign intrigue, it's the most popular of the rain-related names, with a variety of pronunciations—RAY-na, rah-EE-na, or RY-na. Alternate spellings Reyna and Rayna currently rank higher in the US.

A strong, straightforward Irish unisex surname, with a merry glint in its eye, Reagan has been leaping up the popularity lists, to become one of the top girl names starting with R. Some will inevitably link it to President Ronald, but spell it Regan and it's a Shakespearean name: a daughter of King Lear.

Many parents prefer this spelling of Rebecca, used in some versions of the Bible. Still, it's slipped considerably since its heyday in the eighties and nineties.

Riley is the spelling of this lively Irish name most often picked for girls, but this version is occasionally used.

Rhya is the Fertility Goddess of several ancient religions, associated with mothers and pregnant women. In some legends she is the mother of Manann and Verena and wife of Taal. Pronounced rye-ah, similar names from other cultures include Rya, Riya, and Raya.

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.

Can one prominent character affect the gender identity of a name? Definitely, as has supernatural bad girl Ridley Duchannes of the Beautiful Creatures series-turned-movie, played by the gorgeous Emmy Rossum.

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.

Originally a surname deriving from the Roman twin Romulus, this attractive name was introduced to the English-speaking world as a first name by painter Augustus John who used it for his son. Romilly John became Admiral of the Fleet in England.

Rosalie hit its apex in 1938 and then slid straight downhill until it fell off the U.S. Top 1000 completely in the 1980s, only to spring back to life in 2009 as the name of a character in the Twilight series. The beautiful vampire Rosalie Hale has breathed fresh life back into this mid-century name, and the fact that the character is both sympathetic and relatively minor means Rosalie has the chance to thrive again as a baby name without feeling unduly tied to Twilight.

Stylish, gentle, and rustic at the same time, Rowan is a name that falls into various categories. Unisex and cool, mystical and woodsy, with the feel of both Rose and Riley, Rowan is a fresh but familiar choice.

Rue has gone from Golden Girls actress to Hunger Games heroine. This botanical name is also a coincidental double word name, meaning "regret" in English and "street in" French. Despite these unfortunate secondary meanings, Rue has real potential to be one of the most popular new middle names for girls.

Sage is an evocatively fragrant herbal name that also connotes wisdom, giving it a double advantage. It entered the Top 1000 at about the same time for both genders in the early 1990s, but it has pulled ahead for the girls. Toni Collette named her daughter Sage Florence.

Supermodel Christie Brinkley launched an entire name genre when she picked this breezy occupational name for her daughter in 1998, and it has become more prevalent in recent decades.

Counted together, Saylor and Sailor were used for about 1000 baby girls in one recent year in the US, versus about 100 boys.

Alluring and lovely — and much more distinctive now than Samantha or Tamara. Samara is a city in western Russia, a winged seed like the whirlygigs that fall from maple trees, as well as a bona fide first name that could make a more unusual update on Samantha or Mara. It can also be a variant spelling of the Arabic name Samira or Sameera.

Largely male throughout Europe, this name--spelled with or without the c, is an energetic choice that has really taken off for girls here; it's been used for the daughters of Steven Spielberg, Jerry Seinfeld, and Vanessa Williams. The Barack Obamas use Sasha as the nickname for their younger daughter, whose proper name is Natasha. Sasha Alexander, on the TV show Rizzoli & Isles, was born Suzana.

Sasha, largely male in Russia--and also spelled Sascha and Sacha--is an energetic name that has really taken off for girls here, chosen by Jerry Seinfeld (using the alternate Sascha spelling) and other celebs. The Barack Obamas use it as the nickname for their younger daughter, whose proper name is Natasha. But in line with a trend toward softer-sounding boys' names like Asher and Joshua and thanks to Borat star Sacha Baron Cohen, Sasha also still has life as a boys' name too--it's popular in France for boys and girls almost equally.

A place name with a deep Southern accent, the once-obscure Savannah shot to fame, with others of its genre, on the heels of the best seller Midnight in the Garden of Good and Evil, which was set in the mossy Georgia city of Savannah. Originally a substitute for the overused Samantha, Savannah is now becoming overused itself, long among the top girls' names starting with S.

Sawyer is a surname with a more relaxed and friendly feel than many others, and is one of the hottest occupational names right now, with the Nameberry seal of approval.

Used much more often for girls -- about 1000 girls were named Saylor or Sailor last year, versus about 100 boys -- Saylor is a medieval German surname that means ropemaker, which is also related to the occupational name Sailor.
