Fit For A Viking

Despite the success of so many O-starting boys names--Oliver, Owen, Otis, Oscar--Oswald has not yet shown any signs of resurrection, though he does have the animating nicknames Ozzie/Ozzy and Oz. The name has some literary cred--in Chaucer's Canterbury Tales, Shakespeare's King Lear and a novel by H. G.Wells--and there was early cartoon character Oswald the Lucky Rabbit.

Wears long blonde braids, carries a spear, and sings duets with Brunhild. But variations Ottilie, Ottiline, or Ottoline are both unusual and chic.

Ottilie is trending in the UK, where the pronounced T helps the name sound pretty and delicate, rather like Amelie and Elodie. Ottilie is less popular in the US, where many Americans pronounce it as a near-homonym for "oddly".

Otto is cool again. Long a quintessential Old Man Name, Otto has been promoted to trending darling of adventurous baby namers.

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.

Rainer is one of those baby names that is still under-the-radar but has been quietly gaining traction: The number of boys who've received the name has doubled in the past decade, to just under 50. Part nature name and part traditional German name for boys, Rainer can claim a place among the two-syllable r-ending baby names so fashionable for boys today.

European royal name, and to Americans a place-name evoking the majestic mountain in Washington state.

Ralph has two diametrically different images: there's the suave Ralph Fiennes-type Brit (often pronounced Rafe), and then there's the Jackie Gleason blue-collar, bowling blowhard Ralph Kramden bus driver. It's all in the eye of the beholder, though its hip factor did rise when it was chosen for his son by cool U.K. actor Matthew Macfadyen.

Roland is a chivalrous old name made famous by the supposedly eight-foot-tall romantic hero and nephew of Charlemagne, celebrated in medieval poetry and song. It is more widely heard in the US now in its Spanish form, Rolando. You might want to consider rollicking short form Rollo, either on its own or as an abbreviation of Roland. Orlando is the graceful Italian form.

Rollo is a livelier, roly-poly, o-ending version of Roland.

Fairly popular a hundred years ago but out of sight now, the quirky Roscoe deserves a place on every adventurous baby-namer's long list. It joins Rufus, Roman, Remy, Romulus, and Ray as one of the R names that sound fresh again after too many years of Robert, Richard, and Ronald.

Name with connotations both mystical and tragic, newly popular in Europe. For English speakers, though, this name might be ruined by its homonym ruin.

Also spelled Sigfrid, this hefty German name has an appropriately majestic meaning: "victorious peace". Fittingly, a famous bearer was the English World War I poet and pacifist Siegfried Sassoon. Sassoon was named after the hero of a Wagner opera, which in turn was based on a tragic hero from German legend.

The connection to Freud is a strong one, but this German name has a strong and interesting sound and great nickname potential: Ziggy, Iggy, Sim, Sid...

Signy — also spelled Signe — would make another distinctively offbeat alternative to Sydney. Signy appears in Norse mythology as the twin sister of Sigmund.

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.

Idiosyncratic Icelandic singer Bjork chose this name from Norse mythology for her son. It's also an Indian place name.
