Short form of Alfred that had fallen out of favor, but could come back alongside Alfie and other clunky old-style nicknames like Gus and Ike.

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." 
Related names include Asta, a diminutive used throughout Scandinavia, and Astride, the French form. Despite their similarities, Astrid is unrelated to Astra, a Latin name meaning "of the stars."
 
Astrid has never really assimilated into our culture the way Ingrid did, but with the renewed interest in international names, Astrid might be worth consideration by parents with Norse roots. 
 
Astrid is the name of the teenage heroine of Janet Finch's 1999 novel White Oleander and has appeared as a character in How to Train Your Dragon and the TV shows Fringe and Once upon a Time.

This royal Danish name has long  been used across Scandinavia, Germany and Slavic countries and somewhat in the US around the turn of the last century --it was #622 in 1888. There were two notable silent screen stars named Dagmar, one with Polish, the other with Danish roots.

Dagmar

Embla

One of the most popular names in Scandinavia, Freja--or Freyja--was a major deity of Norse paganism. Beautiful, blonde and blue-eyed, she was the goddess of love, beauty and fertility. In the US, the name is most likely spelled Freya.

Gefion

Old Norse name that lives on more appealingly in modern times as Jalmari, short form Jari.

Hjalmar

Hjalte

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.

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."

Pronounced to rhyme with fjord, the Norse god of the sea's name, this would make an unorthodox choice for sea-lovers and fishermen.

Ragnhild

Røskva

Apt name for a little drama queen with a long future ahead of her. Saga is a Top 30 girls' name in Sweden.
 
Saga was the Norse goddess of poetry, storytelling, and history. She was a prophetess — able to predict events.

Thor, the powerful name of the Norse god of thunder, strength and rain, would make a bold statement. Long a comic book staple, Thor has now invaded the big screen, and could land on birth certificates as well.
 Thor Heyerdahl was a famous Norwegian anthropologist/adventurer, author of the book Kon Tiki.
In Norse mythology, Thor was the son of Odin--another crossover name possibility--who was sometimes referred to as Bjorn in Old Norse poetry. Tor is a popular variation (which is also the Hebrew name of a bird that symbolizes the arrival of spring).

Thor

Thyra

Tyr is a very early embodiment of a Norse god, typically thought to guide the law, justice, war and victory.
