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.

Edith was a hugely popular name a hundred years ago that's being revived among stylish parents in Stockholm and London. It's currently beginning to gain traction in the US among those with a taste for old-fashioned names with a soft but strong image.

Helena is one of those classic names that just misses making the US Top 1000 girl names for its entire history, falling off for a single year in 1992. Since then it's been drifting lazily up the charts, and makes a perfect choice if you want a name that both fits in and stands out.

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.

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.

Unlike perennials William, John and James, Edward is a classic that moves in and out of fashion. This royal Anglo-Saxon standard has benefited in recent years from the popularity of the hot hero of the vampire sensation Twilight — Edward Cullen — who has given his name a new infusion of cool.

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.

During its Top 10 heyday in the late 90s and early oughts, Andrew was one of the "cooler" classic boy names, an update on the old guard Roberts and Richards.

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.

Charles derives from the Germanic name Karl, meaning "man" or "free man", and is a royal name in multiple European countries. A famous early bearer is Charlemagne, King of the Franks and Lombards and then Roman Emperor in the 8th-9th centuries.

Sarah was derived from the Hebrew word sarah, meaning "princess." Sarah is an Old Testament name — she was the wife of Abraham and mother of Isaac. According to the Book of Genesis, Sarah was originally called Sarai, but had her name changed by God to the more auspicious Sarah when she was 90 years old.

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.

Albert has acquired a new gloss as one of the top royal baby boy names, a considerable upgrade from its serious, studious image (think Einstein, Schweitzer).

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.

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

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.

Constance is one of the more subtle of the virtue baby names, but still has quite a prim and proper image. One impediment to its revival has been the decidedly dated nickname Connie, though modern parents might well opt for using the strong and dignified name in full.

Catherine is one of the oldest and most consistently well-used girls’ names, with endless variations and nicknames. The Catherine form feels more gently old-fashioned and feminine than the more popular K versions. Most stylish nickname for Catherine right now: Kate...or Cate, a la Blanchett.

Katherine is one of the oldest, most diverse, and all-around best names: it's powerful, feminine, royal, saintly, classic, popular, and adaptable. Long one of the top girls' names starting with K, Katherine has now been unseated on the popularity list by upstarts Kennedy and Kinsley, but a dip in popularity only adds to its charm.

Anastasia is the feminine form on Anastasius, a Greek name derived from the word anastasis, meaning "resurrection." It was a common name among early Christians, who often gave it to daughters born around Christmas or Easter. There are handful of saints named Anastasia, including the patron saint of weavers.
