Fit For A Viking

An ancient German saint's name – and most famously the name of Harry Potter's snowy owl – but the combination of "head" plus "wig" feels a little too literal in English.

Heidi became known—and popular—via the 1880 eponymous children's classic by Swiss writer Johanna Spyri and, despite decades of American Heidis of all sizes, shapes, and personalities, the name seems permanently tethered to that spunky little girl on the Alpine mountaintop in the book and Shirley Temple movie.

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.

Older form of Helge, and a masculine form of Helga.

Short for Brunhilda, the operatic Valkyrie of Teutonic legend, Hilda still has not quite shaken off that image that image. Though with the resurgence of Matilda, she might just have a bit of a comeback.

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

Ingmar is known here almost solely through Swedish director Ingmar Bergman. Ing was the powerful Norse god of fertility and peace, who lent his name to several mortal variations, more notably to English-speakers the female Ingrid.

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.

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.

Kari and all her many sisters, from Carrie to Carey to Kerry and onward, originated for the most part as short forms of either CatherineKatherine or one of the Charles feminizations such as Carol or Caroline.

A strong, powerful choice, ancestor of the modern Superboy Names. Knut is the name of the patron saint of Denmark; Knute Rockne was a legendary Notre Dame football coach. Knute is the middle name of Jessica Simpson's son Ace, in honor of his paternal great-grandfather.

Leif is one of the most recognizable Scandinavian names, thanks to Icelandic explorer Leif Erikson, and is still one of the best, with a pleasant aural association with the word leaf.

The fame of actress and Aerosmith daughter Liv Tyler helped to infuse life into this short but solid Scandinavian name that was chosen for her daughter by Julianne Moore.

Loki is the shape-shifting, gender-bending god of mischief in Norse mythology. Taking several animal forms, from a salmon to a seal to a fly, Loki is alternately friend and foe of the gods.

Matilda is a sweet vintage name that has been gently climbing the popularity list for the past 15 years, after a half-century slumber. The spunky children's book heroine Matilda is one factor in its rise, along with others of its class like Eloise and Caspian.

A medieval German saint's name which remained popular in Germany until the middle of the 20th century. It is still in relatively wide use in other European countries, including Poland and Hungary. With other Bert names – like Robert and Albert and even Gilbert – appealing to lovers of strong, traditional boy names with a slightly clunky charm, Norbert could be one of those so-out-it's-in choices that everyone knows, but almost no one is using.

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.

Olaf, though sainted and regal in Norway, is slightly oafish here. It is one of those names that has become completely familiar in the U.S. without ever becoming assimilated. Now that he's a comical character in Disney's Frozen, he might get some more attention.
