Danish Royal Family

Agathe is a hugely popular name in contemporary France, even if it's English-speaking counterparts have not yet warmed to the usual English version, Agatha. The French pronunciation is sure to trip up non-French speakers.

Alain gives the midcentury Alan a bit of gallic dash.

Alexander has been in a Top 25 boys' name in the US for 30 years now. But namers are still attracted to its imposing historic pedigree.

Alexandra is a name with many international variations, elaborations and short forms, and Alexandrine is one of the more unusual. Another, Alexandrina, was the first name of Queen Victoria.

Andre is one international form that's been familiar in the English-speaking world for decades yet still has not been Anglicized.

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.

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."

The given name Athena was derived from the city name Athens, which is of uncertain origins. In Greek mythology, Athena is the name of the daughter of Zeus who was the goddess of wisdom, warfare, handicrafts, mathematics, and courage, among others. She was the great patroness-goddess of the city of Athens. In the Odyssey, Homer describes her as 'sparkling-eyed Athena.'

This no-nonsense German variation of Charles is strong and sturdy. A top choice throughout the 20th century, Carl is now verging on falling off the charts.

The name Christian has fallen a bit from its 90's and 00's heights, but it's still quite popular. Once considered overly pious, Christian is now seen as making a bold statement of faith by some, while also having secular appeal for others, perhaps influenced by such celebrities as Christian Slater and Christian Bale, not to mention the fashion world's Dior, Lacroix, Louboutin and Audigier.

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.

Elizabeth is one of the most popular girls' names of all time, the female equivalent of James or William. Yet Elizabeth has so much going for it—rich history, broad appeal, and timeless style—that no matter how many little girls are named Lizzie, Eliza, and Beth, you can still make Elizabeth your own.

Felix is one of those ancient but nontraditional names for boys that have come into favor over the past few decades, a favorite of parents who want a masculine name with history and heft that breaks ranks with the standard Franks and Freds. Felix is also an international darling, ranking in the Top 100 in several European and English-speaking countries.

Franz is the German equivalent to Francis, and you'll be hard-pressed to find a Franz outside of countries with Germanic origins. In America the name is often associated with celebrated author Franz Kafka, who was born in Prague.

Despite a return to such feminizations of male names as Josephine, Clementine, and Theodora, starchy Henrietta has not made it into that group. Still, if you look hard enough, you'll see that Henrietta has the same vintage charm.

The long history and solid usage of Henry has infiltrated other cultures, where a number of variations experience the same degree of popularity. In the US, Henrik first entered the Top 1000 in 2014. In Norway, Henrik is a mega popular choice.
