Nature and Bold Middles

Floral, bright, and subtly powerful, Gaia is a name with two separate origins. In Greek mythology, it is the name of the earth goddess and the universal mother, who takes her epithet from the Ancient Greek word for land or ground. It was this ecological element that led actress Emma Thompson to choose it for her daughter back in 1999, and it could hold similar appeal to green minded parents today.

If you like names that are not really names -- some say, the wave of the future -- Harbor has an attractive sound as well as an appealing meaning and image.

Animal names are on the rise, especially more of the aggressive Hawk-Fox-Wolf variety than cute little Bunnys or Robins, and Hawk is a prime example.

Hawk is more commonly heard as a surname, represented by uber-skateboarder Tony Hawk, a pioneer of modern vertical skateboarding. Variations include Hawke, as in actor Ethan, Hawks, as in Golden Age movie director Howard, Hawking, as in scientist Stephen, and Hawkins, as in musicians Coleman, Screamin' Jay and Sophie B, and was recently given to his baby boy by quarterback Tony Romo. There have been characters named or nicknamed Hawk in The Revenant, The Path and Robert B. Parker's Spenser novels. Hawk ranks at Number 699 on Nameberry.

These days, more people will relate to Hermes -- pronounced ayr-MEZ -- as an upscale brand name like Chanel and Porsche than as a Greek god. Actress Kelly Rutherford took on the challenge when she bestowed the name on her son. Hermes is the god of travel, writing, athletics, and thievery, among many other things.

Though the mythological Hero was female, this name might prove too big a responsibility for a little guy to shoulder.

Free and fun name if you don't want to be pinned down to Noelle, Pasqua, or Valentine.

Hunter has been dropping a bit for the past few years but is still one of the leaders of a distinctive band of boys' names that combines macho imagery (Hunter, Austin, Harley) with a softened masculinity. Hunter was for years attached to gonzo journalist Hunter S. Thompson; Josh Holloway used it for his son.

Indigo is one of the most appealing and evocative of the new generation of color names. Color names have joined flower and jewel names -- in a big way -- and Indigo, a deep blue-purple dye from plants native to India, is particularly striking for both girls and boys. Indigo is the name of a character in the Ntozake Shange novel Sassafrass, Cypress & Indigo, and was used for his daughter by Lou Diamond Phillips.

Indigo is one of the most appealing and evocative of the new generation of color names. Color names have joined flower and jewel names -- in a big way -- and Indigo, a deep blue-purple dye from plants native to India, is particularly striking for both girls and boys. Although most people don't think of it like this, Indigo might also be considered among the most stylish Greek baby names in use today. Some cultural references: The Indigo Girls are a folk duo, 'Mood Indigo' is a classic Duke Ellington jazz composition, and there is a 1970's New Age theory that Indigo children possess special, sometimes supernatural abilities. Indigo is the name of a character in the Ntozake Shange novel Sassafrass, Cypress & Indigo, and was used for his daughter by Lou Diamond Phillips.

Iris has so much going for it. It's a fashionable flower name. It's a mythological name, from the Greek goddess of the rainbow. And it's a classic name, always ranking in the girls' Top 1000 but now at its highest point ever.

Isla is a hit name throughout the English-speaking world but hasn't found the same popularity in other western countries, perhaps because its spelling and pronunciation don't make sense for those whose native language is not English. Think island without the final two letters.

The quirky, offbeat and energetic botanical name Ivy is enjoying a deserved revival, propelled even higher by its choice by high-profile parents Beyonce and Jay-Z for daughter Blue Ivy. Ivy is also traditionally used at Christmas, make this one of the perfect names for December babies.

Thanks to two cultural influences, January has joined March, April, June and August as a plausible month name.

Jessamine, a charming name occasionally heard in England, is just beginning to be appreciated in the U.S. as a possible successor to all the Jess names of the past. It's also spelled Jessamyn, as in Quaker novelist Jessamyn West, author of Friendly Persuasion--who started life with Jessamyn as her middle name.

Most things Jul-related – from the month of July to popular modern names Julia and Julian – originate with Roman emperor Julius Caesar, and the month name July is no exception. Fifteen girls and seven boys were named July in 2013, putting this month name into the class of gender neutral names.

June, a sweetly old-fashioned month name derived from the goddess Juno, was long locked in a time capsule with June Allyson (born Ella) and June Cleaver, but is rising again especially as a middle name.

Jupiter's partner Juno has entered the mainstream, so it's possible that her divine mate could follow. But not necessarily for boys — Jupiter is currently mostly female in the US, thanks to its similarity to Juniper. Stars including Ed Sheeran and Ashley Tisdale recently welcomed daughters named Jupiter, which could shift the balance even more towards the girls.

Justice, one of the rare virtue names for boys, entered the popularity ranks in 1992, and has remained on the list ever since. Parents' search for names implying virtue has led to a mini-revival of this long-neglected name in both its German homonymic form, Justus, and as the word itself. Steven Seagal was ahead of the curve when he used it back in 1976.
