For a long time, Isadora has been overlooked in favor of Isabella, owing perhaps to its association with the tragic modern dancer, Isadora Duncan, or because parents would rather their daughter be a Bella than a Dora. Now, with Theodora back in the charts and vintage names in vogue, Isadora has been slowly gaining more attention over the last decade.

Archie made global news as the surprise first name of the newborn royal baby, son of the Duke and Duchess of Sussex aka Harry and Meghan. Archie has now officially transcended Archie Bunker and Riverdale's Archie to take the, um, throne as the quintessential retro nickname name.

Nicholas is derived from the Greek Nikolaos, a name that evolved from the components nikē, meaning "victory", and laos, "people." It shares origins with Nike, the name of the Greek goddess of victory. Nicholas is also a New Testament name that is well-used in literature, such as in Dickens's Nicholas Nickleby.

Robert was the Number 1 boys' name in the US in both 1925 and 1950, and in fact was in the Top 25 for more than a century, giving it true classic status. Strong if not quite stylish, Robert remains in the Top 100 for baby boys as a family favorite.

Serene Irene, the name of the Greek goddess of peace and one of the most familiar Greek goddess names, was hugely popular in ancient Rome and again in the United States a hundred years ago.

Isabella has been a Top 10 name for girls in the US for two decades now. The Latinate form of Isabel, a variation of Elizabeth which originally derived from the Hebrew name Elisheba, Isabella reigned as Number 1 in 2009 and 2010.

Bridget is the Anglicized form of Brigid, an Irish-Gaelic name that was derived from the word brígh, which means "strength."

Frederick, and friendlier nickname Fred, seemed almost to have disappeared, leaving just the memory of Freds past such as Astaire, Mr. Rogers and Flintstone. But today's parents are beginning to recognize it as a strong classic and one of the top royal baby boy names.

Cecily is as dainty as a lace handkerchief. Cecily has a wide assortment of namesakes. One Cecily was the mother of King Richard III, whose beauty gained her the title "the Rose of Raby," Cecily Parsley is a Beatrix Potter bunny, Cecily Cardew is a character in The Importance of Being Earnest, and the author of the Gossip Girl books is Cecily von Ziegesar.

Alfred is up off his recliner! If you're looking for a path to Fred, you can go directly to Frederick or take the long way around with the so-out-it's-in-again Alfred. Alfred is quite popular in several European countries, especially England and Wales, Norway, Sweden, and Denmark.

Since this was the name chosen by the late Roman Catholic pope in 2013, Francis has come into the spotlight.

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.

Frances, a soft and gentle classic last popular a hundred years ago, is trending again. The cool nickname Frankie is one reason for the revival of Frances, adding lightness and sass to a serious name. Frances is the feminine form of Francis, the English variation of the Latin name Franciscus. Franciscus, meaning "Frenchman," was taken from the Germanic tribe the Franks, which got its name from the francisca, the axe they used in battle. Until the seventeenth century, the spellings Frances and Francis were used interchangeably for both sexes.

Beatrix has a solid history of its own apart from Beatrice, with that final x adding a playful, animated note to the name's imposing history and stately vibe.

Louisa, a quaint but strong vintage name, might feel fresher in English speaking countries than old favorite Louise, just as Diana and Julia have more energy than Diane and Julie at the moment. Part of this might just be that Louisa has never been so popular as Louise, so it makes a familiar but distinctive option alongside Eloise, Lucy, Luna, and Lucia.

Strong but sweet, Leah is a classic name that doesn't feel dull or dusty. It's got plenty of dignity, grace, and pluck, making it a solid choice in the 21st century.

Rupert is a charming-yet-manly name long more popular in Britain (where it's attached to a beloved cartoon bear) than in the U.S. Yet we can see Rupert as a more stylish, modern way to honor an ancestral Robert.

Patrick, long tied to a hyper-Irish image, is enjoying something of a renaissance as a stylish classic, as it has long been considered in England. Along with such choices as Charles and George, Patrick has escaped overuse in recent decades.

Diana, the tragic British princess, inspired many fashions, but strangely, not one for her name. For us, Diana is a gorgeous and still-underused choice.

The sophisticated Edmund and its nearly-identical French twin Edmond are coming out of mothballs now that Edward, inspired by Twilight, is once again a hot name. In fact, it's already a fairly popular choice on Nameberry and a solid presence on the England and Wales charts, where it's featured in the latter half since the 90s.
