Nora is a lovely, refined name that conjures up images of Belle Epoch ladies in fur-trimmed coats skating in Central Park. Long seen as a quintessentially Irish name though its roots are not in Ireland, Nora is a quietly stylish favorite that's tiptoed to the top of the popularity ladder.

John reigned as the most popular of all boys' Christian names for 400 years, from the time the first Crusaders carried it back to Britain until the 1950s. Then American baby namers finally seemed to tire of this straight-arrow, almost anonymous John Doe of names, replacing it with fancier forms like Jonathan and the imported Sean and Ian.

Biblical Jacob ceded his Number 1 spot to biblical Noah, in 2013, after holding first place on the list of baby boy names from 1999 to 2012, given a huge boost by the Twilight phenomenon.

Ruth, with its air of calm and compassion, was the third most popular name in the 1890s, remaining in the Top 10 through the 1920s. It's still in use today as some parents tiring of Rachel and Rebecca are giving Ruth a second thought. Some see such Old Testament girls’ names as Ruth and Esther rising on the heels of boy equivalents Abel and Moses.

Sara, the streamlined form of Sarah, makes this ancient name feel more modern, but perhaps a bit lighter weight.

This pet form of Helena and other ena-ending names, long used as an independent name, is attracting notice again as an option both multicultural and simple. Lena was a Top 100 name from 1880 to 1920.

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."

Maren is one of the many twenty-first-century takes on Mary--but we find the more classic Marin spelling preferable. When spelled Maren, the pronunciation seems more clearly to resemble Mary, with the emphasis on the first syllable. Marin, the spelling also used for the beautiful coastal county north of San Francisco, is often pronounced with the emphasis on the second syllable, as in Marie.

With Old European vibes, Johan is a variant of the classic John, similar to the Latin, Hebrew, and Germanic forms, Iohannes, Yohanan, and Johannes. Conjuring up the image of the classical composer Brahms or the astronomer Kepler, while still feeling timeless and distinctive, Johan has been in the US Top 600 for most of the 21st century, helped along by Heidi Klum and Seal using it for their son in 2006.

The ubiquitous French version of Mary came into the English-speaking world in the nineteenth century. In the United States, Marie was a huge hit at the turn of the last century and for the ensuing fifty years, becoming the seventh most popular name in the country for three years, from 1901 to 1904.

The name of the sainted mother of the Virgin Mary was among the top girls’ names for centuries, in both the original English Ann spelling and the French Anne. Both left the Top 100 around 1970 but Anne is still among the most classic names for girls, although others are more likely to choose the original Hannah, the Anna variation, or even Annabel or Annabella.

Oline is an old school feminization of the classic Scandinavian names, Ole or Olaf, whose light, timeless sounds means it still ranks in the Norwegian Top 100 today.

A very Christmas-y Christmas baby name, that may avoid the Santa image by instead adopting the alternative spelling Klaus.

Bjorn is one of the most recognizable Scandinavian names, 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.

Karen, a once sweet Danish import, was so popular during the baby boom (Karen was Number 3 in 1960) that it's become a mem in recent years, representing a hostile white woman—one who usually wants to speak with the manager.

Johanna is the version of this name used in Holland, Germany, and Scandinavia. The extra h makes Johanna a slightly more dignified version of Joanna.

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.

Short but substantial Nordic name that travels well -- although it runs the risk of being confused with all the feminine Jen names.

Whether it's pronounced with an "een" or an "aine" or an "enn" sound at the end, Helene doesn't feel as current the more forthright Helen or the airier Helena. Helene reached a high of Number 228 in the US in 1916, when ene, ine and een names were all the fashion, and stayed in the Top 500 until 1962, making a final exit in 1970. It still ranks well in its native France, and even more in Norway (#70). Model Heidi Klum's daughter 'Leni' has Helene on her birth certificate.

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.
