As modern as it sounds, Blaise is an ancient Christian martyr name. In Arthurian legend, Blaise is the name of Merlin the Magician's secretary. Its relation to the word and name Blaze gives it a fiery feel. Amanda Beard named her baby boy Blaise Ray.
 Saint Blaise, an Armenian bishop, is the patron saint of wild animals and those with sore throats.

Bodhi is a Sanskrit name translated as "enlightenment" or "awakening" which relates to a Buddhist concept, wherein Bodhi is synonymous with the state of nirvana, being freed from hate, greed and ego.

Since then it has been used by four celebrity couples as the first name for their sons, and celebrity chef Tom Colicchio as the middle name for his boy, Luka.

As opposed to some other religious and <a href="https://nameberry.com/list/254/spiritual-baby-names">spiritual names</a>, Bodhi has an upbeat, friendly feel, similar to that of Brody and Cody.

 Similar but less word-like: Kenyon.

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 <a href="https://nameberry.com/baby-names/167/greek-names">Greek baby names</a> 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.

Knox is an old Scottish surname that Brad Pitt (whose great-great-grandfather was named Hal Knox Hillhouse) and Angelina Jolie took out of the back cupboard, dusted off, and elevated to coolness--to the point where it entered the <a href="https://nameberry.com/popular-names">popular baby names</a> list in 2009. Knox now ranks among the most influential <a href="https://nameberry.com/fameberry">celebrity baby names</a>.
 With Knox, the Jolie-Pitts established their own tradition: instead of their sons bearing the same first inital, they share the final letter 'x'--Maddox, Pax and Knox-- as well as a final 'n' for their <a href="https://nameberry.com/list/673/middle-names">middle names</a>.

Evocative modern unisex choice brought into the spotlight by actress Lake Bell.

St. Landry was a seventh century bishop of Paris, founder of the city's first hospital. The name is more familiar in recent years thanks to legendary Dallas Cowboys coach Tom Landry, an association that makes this a sports hero name, as well as a thoroughly masculine one. Landry is also in use for girls in the US. Landry is one of the oldest surnames in France, dating back to the medieval period, and is particularly popular among Cajun-Americans. It has been on the Social Security list since 2010.

Leif is one of the most recognizable <a href="https://nameberry.com/baby-names/173/scandinavian-names">Scandinavian names</a>, thanks to Icelandic explorer Leif Erikson, and is still one of the best, with a pleasant aural association with the word leaf. 
 Leif Erikson, son of explorer Eric the Red, was the first European to land in North America--some five hundred years before Columbus. Centuries later, the name became associated in the U.S. with 1970s teen idol Leif Garrett, the name peaking on the charts at Number 654 in 1970, dropping off completely in 1987. It climbed back onto the Top 1000 in 2014.
 Pronounced LAYF in its Scandinavian milieu, Leif and Lief are sometimes pronounced as Leaf in English-speaking countries. Joaquin Phoenix was for a time known as Leaf, in keeping with the <a href="https://nameberry.com/list/329/nature-baby-names">nature names</a> of his siblings.

Navy

As sturdy as Oak, with deeper roots. It's been on the rise for both boys and girls in recent years, with the name comfortably in the top 500 for boys and nearing the Top 100 for girls.

For boys, Oak variations Oakland, Oaklen, and Oaklee are also quite popular. And S-ender Oaks or Oakes are also gaining in popularity.

Though it may sound like a modern unisex invention, Oakley was actually used as a boys' name in the US at the end of the 19th and early 20th centuries. It's popular throughout the English-speaking world as well as for dogs.

Oakley

Unlike Pearl and Ruby, this is one gem name suited for boys, the final x making it sound strong and virile. Musician Iggy Azalea chose the name Onyx for her son.

Attractive North Carolina place-name and surname of explorer Sir Walter Raleigh.  Distinctive, classy-but-approachable choice for either sex.

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

Ripley

Salem is a Biblical place name in Canaan, believed to be the same as Jerusalem, as well as the Massachusetts town famous for its late 17th century witch trials. Salem is also a popular first name in its own right throughout the Arabic world.

In the US, about 400 babies of both genders were named Salem last year, but it's difficult to say how many of those were given the Biblical place-name and how many the Arabic version of the name. About 40 percent of the Salems were boys, with a significant number of baby boys given an alternate spelling of the Arabic name, Salim. 

One negative association of the name, the menthol cigarette, went out of business in 2019

Salem

Shiloh

Sky is an ambigender nature name that was first legitimized as the character of Sky Masterson in the 1950 musical Guys and Dolls, played in the film version by Marlon Brando. It's a name we appreciate for its clear, wide-open feel, less hippyish than others like Rainbow and Starlight, and makes an appealing middle name possibility.
 Sky is the name of Sophie's fiance in Mamma Mia, and there are both Power Rangers and Transformers with the name. Elizabeth Berkley used it for her son.
 It is also spelled Skye, as in the island in the Inner Hebrides of Scotland. Plus, it's a logical nickname for the variously spelled Schuylers and Skylers.

The girls have dibs on Spring, Summer, and Autumn, leaving this name evocative of snowy landscapes as the one possible seasonal choice for boys. And naturally, it's one of the most obvious <a href="https://nameberry.com/list/89/winter-baby-names">names for winter babies</a>.

Winter

Wylie is a friendly, nonchalant rodeo name with an almost irresistible charm; parents may pick up on its pleasant similarity to the more popular, unisex Riley. Although more masculine, we see Wylie as working as well for boys and girls (Richard Anderson used it for his daughter in 1999). Wylie (or the interchangeable Wiley) can also be an original and authentic way to honor an ancestral William. We don't, however, recommend you spell the name the way Corey Parker did: Wylei. Why lay?
 Wiley Post was the first to solo pilot a plane around the world, and contemporary foodies know Wylie Dufresne as a renowned chef, a leading proponent of the molecular gastronomy movement. Elinor Wylie was an inspirational poet.

Wylie

Wynn or Wyn is a Welsh male name deriving from the very productive gwyn element, which forms part of all Welsh names ending -wyn or -wen, as well as the Gwen names and the Irish Fin- names. Wynn is a soft and gentle yet sturdy choice which feels quietly timeless and charming.

 On Sons of Anarchy, Zeke is spelled Zeek. Dallas Cowboys running back Ezekiel Elliot goes by Zeke.

Zeke

If you're looking for a name that's light and breezy, this could be it.

 Robby Benson and Karla De Vito named their son Zephyr in 1992, and Zephyr Benson is now an actor himself. More recently it was chosen by tech entrepreneur Sean Parker for his baby boy.
