Agnes is the Latin variation of the name Hagne, which itself derived from the Greek word hagnos, meaning "chaste." In medieval times, St. Agnes was a very popular saint, leading to its popularity as a girl's name. Agnes Grey is the title of one of the two novels written by Anne Brontë.
 
Agnes, though it was the third most common English girls' name for four hundred years, has long been stuck in the attic. But now it looks like Agnes was so far out it's just about ready to come back in. It did look cute on a little girl in Despicable Me, and nickname Aggie has lots of retro appeal. 
 Agnes has also been making inroads in the celebrisphere—first actress Elisabeth Shue chose Agnes for her third child, and more recently Jennifer Connelly and Paul Bettany named their daughter Agnes Lark. 
 The French pronunciation—ahn-YEZ—could make it more attractive, but few Americans would comply. Other interesting variations: the Welsh Nesta, the Latin/Scandinavian Agneta, the Spanish Inez/Ines/Ynez, and the Scottish Senga—which happens to be Agnes spelled backwards.

Ari, the short form of Ariel (or any other Ari- beginning name, such as Aristotle) stands up better as a <a href="https://nameberry.com/boys-names">boys’ name</a> than its progenitor does. It is also short for Aristotle, as in Onassis, and is a prominent character on TV's Entourage -- the uberagent Ari Gold. 
 Among other notable bearers have been Ari Fleischer, White House press secretary for President George W. Bush and Ari Emanuel, powerful talent agent and possible inspiration for Ari Gold.
 Ari Ben Canaan is the main character in the Leon Uris novel Exodus, played by Paul Newman on screen, and Ari is the name of one of the Tenenbaum sons in The Royal Tenenbaums.

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 Elin variation makes an old favorite sleeker and more modern. Elin came to prominence via the ex-Mrs.Tiger Woods and is now perhaps best known via novelist Elin Hildebrand.. It entered the US Top 1000 in 2010, though it's now dropped off again.

Gunnar

Though familiar to all via such childhood icons as Hans Brinker, Hans(el) and Gretel, and Hans Christian Andersen, few Americans have chosen this name for their sons because of its intractably Old Country image. 

Hans

A traditional Nordic name, Helga was extremely popular throughout Scandinavia in the 19th and early 20th centuries. In Germany, it was a Top 10 pick from 1924 to 1943. And it still ranks in the Icelandic Top 50 today.

 In the English-speaking world, Helga has been associated with a series of unfortunate characters in popular culture, from the wife of Hägar the Horrible in the comic strip of the same name, to Helga Pataki from the kids' TV show Hey Arnold!. But more recent, more positive Helgas – like Helga Hufflepuff, one of the four founders of Hogwarts, and a character in the drama series Vikings – could redeem the name.

 Helga's Russian cognate, Olga, is a classic there, and still ranks in the Russian Top 50 today.

Magnus is a Latin name, literally meaning "greatest," that has a Scandinavian feel. It dates back to Charlemagne being called Carolus Magnus, or Charles the Great. Norwegian king Magnus I, named after Charlemagne, introduced it to his culture, and thus Magnus was the name of six early kings of Norway and four of Sweden. It is still a highly popular name in Denmark and Norway.
 
Magnus, a powerful name with a commanding presence, is one of the newly unearthed ancient artifacts. It was picked for their sons by Will Ferrell (whose wife Viveca Paulin is Swedish), Kristy Swanson, and Elizabeth Banks—likely credited for this name's jump into the Top 1000 for the first time in 2013, as one of the year's fastest-rising names. Its fashionable s ending may keep it in popular use.
 
Magnus has made appearances as a vampire in Anne Rice's Vampire Chronicles and as a character in Roald Dahl's Matilda. And for an extra ego boost, in Charles Dickens's The Pickwick Papers, there's the following dialogue: 
 "'Magnus is my name. It's rather a good name, I think, sir.'
 'A very good name, indeed,' said Mr. Pickwick."
