Kate and William shocked the world when they announced that they'd named their third child Louis, or Prince Louis Arthur Charles, to be more precise. But we've been predicting a comeback for this classic name for a long time.

Louise has for several decades now been seen as competent, studious, and efficient—desirable if not dramatic qualities. But now along with a raft of other L names, as well as cousin Eloise, Louise is up for reappreciation—sleek and chic, stylish in Paris, and starting to become so in the US as well. Louisa is perhaps more in tune with the times, but Louise has more edge. Louise has been on the rise lately, and reentered the US Top 1000 for the first time in a quarter century in 2016.

Lucille is a name that had long been overpowered by its link to Lucille Ball, with an image of tangerine-colored hair, big, round eyes, and a tendency to stage daffy and desperate stunts. But with the newfound craze for double-L names like Lily and Lila, Lulu and Luna, and as the choice of Lucille by hipster parents Maya Rudolph and Paul Thomas Anderson, Lucille is breaking free from its old clownish image, moving rapidly up the charts over the past decade after a long nap.

Liana is a pretty, graceful and simple name that doesn't fall flat. The name of a flowering tropical vine that grows in forests, it's an international gem that works well in multiple languages.

Sophisticated Gallic version of Lucian, Lucien may appeal to parents attracted to this meaning over that of Lucas and Luke, which have a different root, and also looking for a more unusual choice.

Straightforward single-syllable name, though children named Lyle may get tired of hearing "Lyle, Lyle, Crocodile". Lyle was at the height of fashion in the 1920s, which makes him due for a comeback right about now. The double L certainly gives it a fashionable sound.

Sweet Lorraine might just be old enough to be ripe for reconsideration. This French place name has moved in and out of fashion in the few hundred years it's been used as a girls' first name, somewhat influenced by the alternative name of Joan of Arc--Saint Joan of Lorraine. It was quite popular from the 1920s to the fifties, but has pretty much been in limbo since then.

Lou is usually a short form of Louise, Louisa, or Lucy in English-speaking countries, when Lou is used for girls at all. But in France and Germany, it's a fashionable choice all on its own, sure to gain even more widespread style credibility since Heidi Klum and Seal chose it for their daughter.

In Arthurian legend, Lancelot was one of the most dashing of the Knights of the Round Table who eventually had an affair with Queen Guinevere: it makes for a romantic story-- but perhaps overly romantic-- name.

Lowell is an upstanding and somewhat conservative name that calls to mind the genteel patrician families of nineteenth century New England, such as the one poet Robert Lowell was born into. Two other Lowell-surnamed poets are Amy and James Russell.

Leroy's heyday was in the early twentieth century, when it was in the US Top 100 until 1949. As a result, it's now more frequently seen as a father or grandfather name. Nevertheless, it remains in the latter end of the US Top 1000, perhaps passed down from father to son, or similar enough to popular Levi that it still appeals.

Lisette, also spelled Lizette, is a dainty,, if somewhat dated, Gallic offshoot of Elizabeth. It reached its U.S. peak of popularity in 1999, then fell off the list in 2001.

Linda begat Lynn which gave way to Lynette, which peaked in the late 1960s. Lynette has been off the Top 1000 for a couple decades now, and the Lynn variations finding the most favor are those that put the "lyn" part at the end: Evelyn, Madelyn, Brooklyn.

St. Landry was a seventh century bishop of Paris, founder of the city's first hospital, though in the US, it may be better connected with legendary Dallas Cowboys coach Tom Landry, an association that makes this a sports hero name with a hint of ruggedness. Familiar in France between the 1970s and 2000s, it also featured at the latter end of the US Top 1000 during the 20210s.

Popular in the 1930s in France, this is a diminutive of Lucy (or Lucie).

A French accent makes almost everything sound better, especially when attached to a Twilight vampire. Laurent also has a high-style feel via designer Yves St-Laurent. Laurent de Brunhoff is the French author-illustrator who continued his father Jean's series of Babar books. 

Sweet, enchanting Lilou is considered both a pet name from the Occitan language (spoken in Provence in the south of France), and a compound name, blending floral Lili with classic Louise. It peaked in France back in 2009 when it reached #12, and while it has now fallen in popularity, it remains in the Top 200.

Luis has long been one of the most popular Hispanic names in America — it was in the Top 100 every year from 1980 to 2014, though it's dropped a bit in popularity. It's familiar, yet would add a worldly touch to a basic surname.

Swaggering western place-name with a lot of cowboy bravado and panache.

Although the accent in Linnet is on the first syllable, it could be confused with the dated Lynette.
