Names from Whats My Line

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.

A combo name that was used in the early 19th century, but has always been overshadowed by its sleeker counterpart, Luella. By blending Ella with Louise, Louella could mean "battle famous fairy maiden" and using the 'Lou' spelling means it remains more closely tied to Louise which may be more appealing to anyone hoping to use it as an honor.

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

Louisa, a quaint but strongvintage name, is an example of the idea that these days, old-style girls’ names are more fashionable when they end with an a rather than with an e, as in Julie/Julia, Diane/Diana. So for the next generation, Louisa may rise again, especially with the growing popularity of other Lou/Lu-starting names, like Lucy and Luna. Louisa reentered the US Top 1000 in 2014 after a 45 year absence.

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.

As heavy as a marble bust of Beethoven.

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.

This streamlined Italian and Spanish spelling of Louisa is currently very popular in Germany, Austria, Switzerland and Portugal, where it's usually spelt Luísa.

Lynn arrived in the 1940s, spinning off from the wildly popular Linda, to become a top midcentury middle name. Now, Lynn's in limbo.

Mabel is cuddly Victorian favorite rising in popularity in the US, after a 50-year nap If you love offbeat old-fashioned names like Violet or Josephine, only sassier and bubblier, Mabel is one for you to consider. It is currently in the US Top 200 and the UK Top 50.

Sophisticated and sweet, delicate but substantial, Madeleine is the classic French variation of Magdalene.

A super diminutive nickname name, and sometime Madonna nickname – it was how the British tabloids referred to her when she moved to London in the 1990s, which she found annoying until then husband Guy Ritchie said it stood for 'Your Majesty'. Madge Undersee is Katniss's best friend in The Hunger Games books.

Magnus is a Latin name, literally meaning "greatest," that has a Scandinavian feel. It dates back to Charlemagne being called Carolus Magnus, or Charles the Great. Norwegian king Magnus I, named after Charlemagne, introduced it to his culture, and thus Magnus was the name of six early kings of Norway and four of Sweden. It is still a highly popular name in Denmark and Norway.
