Abel, the name of Adam and Eve's unfortunate younger son, compensates with positive connotations: capable, competent, ready and willing. 
 Abel has literary connections to the novels of Dickens and Trollope, and is also one of the few well-known Old Testament names not plagued by overuse. Having been chosen for their second son by Amy Pohler and Will Arnett could give it a real popularity bounce.
 Abel's namesakes include two movie directors, Abel Gance and Abel Ferrara, and a pop singer, Abel Tesfaye, more commonly known as The Weeknd.

Hot young actor Alden Ehrenreich, the new Han Solo, gives this formerly-stodgy surname name an attractive new image, making it a fresh successor to Aiden or Holden. Before it got this fresh shine, Alden was among the classic <a href="https://nameberry.com/list/645/delicious-thanksgiving-names">Thanksgiving baby names</a>.

Alden

A male Biblical name meaning healer, Asa is also an international gem. In Japanese, it means "(born in the) morning". And in Scandinavia, where it's generally spelled Åsa or Ása and pronounced O-sa, it's a popular diminutive form of Old Norse names beginning with the element áss "god".

Bjorn is one of the most recognizable <a href="https://nameberry.com/baby-names/173/scandinavian-names">Scandinavian names</a>, thanks in large part to tennis great Björn Borg, winner of five consecutive Wimbledon singles titles and six French opens and something of a rock star figure.
 
Bjorn has been in use since the days of the Vikings, but got a boost in popularity when Borg ruled the courts. There have also been other notable Bjorns in various fields in Sweden, Norway and Germany, ranging from the first king of Norway to a member of the pop group ABBA.
 
And if you do pick this name for your son, your baby Bjorn can be carried around in a Baby Bjorn.

The dynamic personality and paintings of Mexican artist Frida Kahlo have inspired growing numbers of parents to resurrect this form of the name. It does much better in certain European countries, especially in Denmark and Norway. The Frieda and Freida spellings were more popular in the US until the middle of the 20th century.

Frida

Flain

Flane

Pronounced zheel, it's a dashing conquistador; as gill, it's the nice and slightly boring guy down the street. 

The Old Norse god Óthinn was also known by the epithet Grímr — translated into Middle English as Grim.

Grim

The kind of nouveau macho name favored by NRA-leaning parents. Killers' frontman Brandon Flowers gave it to his son in 2009. Gunnar is another spelling that makes the name a bit less militaristic.

If you fit this definition, this might be a clever choice, especially as a middle name. 

Haldan

The name of the last Anglo-Saxon king of England before the Norman conquest, and a name that's long been associated with a pipe-smoking, bespectacled grandpa or uncle.
 
After years in style limbo, Harold is slowly making a comeback, possibly boosted by cheerful nicknames like Harry and Hal. Filmmaking couple Greta Gerwig and Noah Baumbach have a son named Harold.

Harold

Howard, once hugely popular -- in the Top 50 from the 1870s to early 1950s, hitting Number 24 in 1920 -- has been stuck in Dad-Grandad limbo for decades, but is showing some signs of stirring back to life. Along with such formerly-fusty names as George and Harold, Howard may soon feel baby-appropriate, perhaps with the short form Ward.
Howard was the surname of an early English noble family, gradually metamorphosing into a first name in the nineteenth century. Notable Howards include tycoon Howard Hughes, director Howard Hawks, politician Howard Dean, and media figure Howard Stern. In literature, there is Ayn Rand's iconic architect Howard Roark, protagonist of The Fountainhead.
 Strange trivia item: Vampire novelist Anne Rice's given name is Howard Allen. She has said her mother "had the idea that naming a woman Howard was going to give that woman an unusual advantage in the world."

Ing was a powerful Norse god whose name inspired several modern variations -- though Inga has become a caricatured Scandinavian choice. 

Inga

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.
 Still popular in its native Scandinavia, where it is a royal name, its highest US ranking was Number 380 in 1967. 
 Its meaning refers to Ing, the Norse god of fertility, peace, and prosperity, and he's looked upon as the ancestor of the Swedish kings.
 Ingrid was the name of mother figures in both Spy Kids and White Oleander.
 Trivia tidbit: It's Scarlett Johansson's middle name.

Ingrid

Iver is a popular name in its native Norway, but parents in the U.S. are starting to take note of this rugged yet gentle name. Stemming from the original Norse name Ívarr, it is part of a small group of names with similar roots: Ivar, Ivor, Ivo, Ives, and Evander. It was brought to England by Scandinavian settlers in the Middle Ages, and to the US by in the 19th century.
 
Some of the American parents picking up on this name may attribute it to the indie folk band Bon Iver, founded by Justin Vernon who pronounces the latter half ee-VAIR.
 
No matter how you say it, Iver is making headway on this side of the Atlantic with a little under 100 boys receiving the name each year. This includes supermodel Coco Rocha, who picked Iver Eames for her son born in 2018.

Iver

A European nickname for Katherine variations.

Kata

Ragna

An fearsome old Norse name with a long history in Scandinavia. It's gotten a boost in the States from popularity of the History Channel drama "Vikings," in which the protagonist is named Ragnar. Ragnar Lodbrok (meaning "shaggy pants") was a legendary warrior whose story was told in the Viking sagas. Ragnar also recalls name of the Norse Judgment Day, Ragnarök. Easier versions here would be Raynor or Rainier, as in the late prince of Monaco.

Ragnar

This intriguing Scandinavian name is associated with Roald Dahl, author of the juvenile classics James and the Giant Peach and Charlie and the Chocolate Factory. You can honor an ancestral Ronald just by dropping that middle 'n'.

Roald

Like Papa name Rudolf, Rolf never quite emigrated from the Bavarian Alps.  You might want to move on to Rollo or Wolf.
