Fairly popular a hundred years ago but out of the US charts since 1978, the quirky yet edgy Roscoe feels very much in step with the trending o-ending boy names popular now, such as Milo, Hugo, and Otto. A Top 1000 choice in the UK (albeit near the latter end), it could make a cool alternative to Ross, Russell, Robert, and Ronan.

Freya has long been popular in the U.K. but has only taken off in the US in the last decade, along with the entire category of mythological names. Derived from the Old Norse name Freyja, meaning "Lady, noble woman", Freya is the name of the Norse goddess of love, beauty, and fertility.

Astrid has been a Scandinavian royal name since the tenth century, and many people associated it with the Swedish author of the Pippi Longstocking stories, Astrid Lindgren. Astrid is derived from the name Ástríðr, which is made up of the Old Norse elements that mean "god" and "beautiful."

Hallie -- it rhymes with alley and is not to be confused with Halle or Hailey or Holly -- is one of those comfy nicknamish names that are in favor in these complicated times.

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

Eric is derived from the Old Norse name Eiríkr, from the components ei, meaning "ever," and ríkr, "rule." It was adopted by English speakers in the mid-nineteenth century, who were already familiar with the exploits of the tenth century Viking navigator and discoverer of Greenland, Eric the Red. Erik is an alternate spelling and the preferred form of the name across much of Europe.

The luminous Ingrid Bergman's appeal was strong enough to lend universal charisma to this classic Scandinavian name, which has been somewhat neglected in the US. Even today, a child named Ingrid would be assumed to be of Scandinavian ancestry, signaling the name has never been fully integrated into the English lexicon the way other European choices from the same era like Danielle or Kathleen have.

Kara and the soundalike (though not necessarily related) Cara are among the most multi-cultural names around. Cara has roots in Latin, Italian, Irish, Spanish, and Portuguese, and Kara can be viewed as simply as K-starting version of Cara.

Odin is the name of the supreme Norse god of art, culture, wisdom, and law — who was handsome, charming, and eloquent into the bargain. The name projects a good measure of strength and power and has excellent assimilation potential.

Idony is a Medieval variation of Idonea, itself an English form of Iðunn, the Norse goddess of spring and eternal youth. She was notable for carrying, keeping, and guarding the box of apples from which the gods would eat to regain their youth.

A popular name in Denmark, in this country Bo has some cowboy swagger and a lot of substance in its minimal two letters. In Mandarin Chinese, Bo means "wave".

Dustin's popularity in recent years has probably had more due to its similarity to Justin than to idolization of Dustin Hoffman -- himself named after silent screen cowboy star Dustin Farnum -- who certainly was the one to put it on the name map. In recent years, golfer Dustin Johnson has brought fresh renown to the name. Dustin is a character in Netflix hit Stranger Things. After decades in the spotlight, Dustin feels like a classic rather than an upstart. It peaked in the Top 50s in the 1980s.

Closer to the original Norse name Ívarr, it is part of a small group of names with similar roots: Ivor, Iver, Ivo, Ives, and Evander, which all make rugged yet gentle feeling choices. Used throughout Scandinavia, Ivar is in the Swedish Top 100 and is also on the rise in the UK, outranking the English variation, Ivor.

A strong, if slightly dated sounding choice, Ronald made the US Top 10 in the late 1930s through into the mid-1940s, before it became heavily associated with President Reagan, as well as with the McDonald franchise mascot. More recently, it has appeared in the Harry Potter series, borne by Ronald "Ron" Weasley, while others may immediately think of its rhyme, Donald. All of these factors may work against Ronald making a big resurgence, but popular nickname Ronnie might make others reconsider.

Sigrid is a distinctly Scandinavian name that is starting to edge out into the wider world, a la cousin Ingrid. Unfortunately, short form Siri is now off the table, but Sigrid is still a possibility.

Liv combines the succinct charm of a nickname—people might assume it's short for Olivia—with the solidity of being a classic stand-alone Scandinavian name with a life-force meaning. It was brought into the public eye (in the English speaking world that is) due to the fame of actress and Aerosmith daughter Liv Tyler.

Though Tate is used almost exclusively for boys, we can see Tate as a stronger surname alternative to Kate or a clipped form of Tatum.

Once a common boy name in Ireland, the dynamic Darby now has a definite unisex feel. A bit like a mash up between Darcy and Ruby, it appeared in the US Top 1000 in the 90s, peaking in 1995 when it reached #499. It's likely this sudden interest in Darby was owing to the 90s book and film, The Pelican Brief, starring Julia Roberts as a law student called Darby.

The straightforward Erica is a Norse feminization that was long associated with the complex, mega-popular character Erica Kane, played by Susan Lucci for decades on the soap opera All My Children. Used in Scandinavia since the early eighteenth century, where it was usually spelled Erika, it was in the Top 50 girls' list in the USA in the 1970s and eighties.

Spirited and bubbly, but handsome and preppy too, Darby is a surname style choice that fits in well with the likes of Alby and Lennox.
