Gender defying

Quinn is an engaging Celtic surname that is still on the rise for girls but beginning to flag for boys. As a female name, Quinn is in the Top 100, used for over 3000 baby girls last year, but toward the bottom of the Top 500 for boys, given to 700 baby boys.

Mostly feminine, though "Office" star Rainn Wilson gives it a slight masculine twist. You might also use this as a short form of Raines.

A preppier take on Rain — you could also consider Raines. The feminine version of Raine is French, related to Reina, and means "queen."

Ray, still and forever, is one of the all-time hippest boys' names, with its jazzy Ray Charles biopic overtones. It's one of the coolest middle names), but works perfectly fine as a first.

Reign is one of a new, ahem, kingdom of word names that suggest a high-born child, joining Royal, Lorde, Titan, Saint, King, Princess, and Noble. We predicted this kind of defining name to be the Number 1 baby name trend of 2015...two weeks before Kourtney Kardashian and Scott Disick named their third child, a boy, Reign.

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.

Roux is the name of the dashing Johnny Depp character in Chocolat. Roux is French from a Latin word meaning russet or brownish red; it's also a cooking term for a mixture of flour and butter that forms the foundation of many gravies or sauces. Most of today's children with this name, pronounced roo, will actually spell it Rue, for the female character in The Hunger Games.

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.

Botanical choice that can work for either gender. Simple and straightforward. Caveats: rue means "regret" in English, and "street" in French.

Sonny is one of the generic boy nickname names making a surprise reappearance, and it was recently used by actor Jason Lee. Another surprise: It's been on the US Top 1000 list every year since 1927, reaching a peak in 1975, when it hit Number 428.

Upbeat nickname-name that can't help but make you smile, along with its soundalike Sonny.

A strong single-syllable surname with a joyful meaning, Tate is finding a place on more and more birth certificates.

Valentine is an attractive Shakespearean name with romantic associations, but those very ties to the saint and the sentimental holiday have sent it into a decline, one which we think may be about to turn around.

Wren may not be as time-honored a bird name choice as Robin or even Lark, but it's more fashionable and fresh, with a gentle and earthy vibe.
