We're hearing Kat more and more being used by Katherines who are tired of Kathy, Kate and Katie. Katti or Kattie is another possibility.

Kay, a cigarette-smoking, nightclubbing name of the 1930's, could be ready for a comeback along with cousins May/Mae and Ray/Rae.

Actor Kit Harington, aka the dreamy Jon Snow on Game of Thrones, has given this nickname-name new style and appeal for boys. Actress Jodie Foster used it for her son.

Kya, a variation of the popular Kaia, the feminine form of the also-popular gender-neutral name Kai, was one of the fastest-rising girls' names of 2023.

With the rising popularity of Kai, this more phonetic spelling has been gaining traction as well. Kye debuted in the US Top 1000 in 2015, and was one of the fastest-rising names of the year in 2016.

While traditionally pronounced as a homonym for Lee, Glee actress Lea Michele pronounces her name like Leah, and it may also rhyme with Freya. Regardless of your preferred pronunciation, it's interesting to note that Lea has always charted in the US Top 1000, despite coming close to the bottom a few times, making it one of the girl names starting with L that both fits in and stands out.

A name that has a bit of a shouldn't-I-be-a-middle-name sound, though still in use as a first for both genders. Lee might be a good choice if you want something that sounds at once traditional yet modern, unisex but not newly-minted.

Leo is a strong-yet-friendly name that was common among the Romans, used for thirteen popes, and is now at its highest point ever in the US thanks in part to Leonardo "Leo" DiCaprio.

Short, sweet, and clear, Lia is used throughout Europe, across America, and in some areas of Asia and Africa, making it a truly international and versatile choice.

Lou, all by itself, is become fashionable for girls, which usually makes a name LESS fashionable for boys. But Lou, like Bill or Jim, is rarely used on its own for boys anyway. (You wouldn't name a boy Frederick Lou the way that girls are named Mary Lou or, in the case of Keri Russell's new baby, Willa Lou.) Long form Louis is getting cool again and, with the Lewis spelling, is the Number 2 name in Scotland.

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.

This name of a character played by Kirsten Dunst in the movie Virgin Suicides, originally a novel by Jeffrey Eugenides, is gaining attention, also thanks to the heroine Lux, Lady of Luminosity in the League of Legends games. Luz is the Spanish version.

Pronounced LOOSE, this name that refers to the Virgin Mary—"Our Lady of Light"—is one of the most widely used Spanish name for girls. Its sleekness and stylish final z gives it a modern appeal, like sister name Lux. Nicknames and variations include Chitta, Lucecita, Lucelida, Lucelita, Lucha, Lucida, Lucila, Lusa, and Luzana.

In Ireland and Scotland, Mac and Mc mean "son of"; here, Mac is a generic fella, or a short form cooler than either Matt or Max. Mac can be a nickname of any longer Mac or Mc starting name such as McCoy or Macalister. If you want to make it feel more complete, you can always spell it Mack.

Mae, a sweet and springlike old-fashioned name, hadn't been on the national charts in forty years, but finally made it back in 2010. Mae is derived from May, the month name that was chosen for its connection to Maia, the Roman goddess of growth and motherhood.

Max was derived from Maximilian, a Latin name that originated from the Roman family name Maximus. The character name Max in the children's classic Where the Wild Things Are had an impact on baby namers. Max is a widely used name internationally.

May is a sweet old-fashioned name that hasn't been on the national charts in several decades, but is definitely sounding fresh and springlike. Parents are beginning to see it once more as one of the prettiest middle name options. May was as high on the list as Number 57 in the 1880s; it's now 228 on Nameberry.
