The Suite Life of Zack and Cody

Though the fuller Lancelot has for the most part been shunned as a 'too-much-name' name, the short form Lance has been consistently in or around the Top 500 since 1938, climbing as high as Number 76 in 1970. It was used as a character name by Walter Scott as far back as 1823. Lance is also the name of a medieval weapon, making this name all boy.

Laura is a hauntingly evocative perennial, never trendy, never dated, feminine without being fussy, with literary links stretching back to Dante. All this makes Laura a more solid choice than any of its more decorative counterparts and one of the most classic girl names starting with L.

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.

Nickname of yesteryear now saddled with all manner of unattractive associations. Any Leonard of today would be called Leo, or maybe Leon or Leonard (or much more fashionably, Leonardo).

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.

A Scottish place and surname that was once adrogynous but now leans about 20 to 1 toward the girls' side, Leslie has a pleasant, heathery feel that kept it in or near the Top 100 for several decades; the Lesly and Lesley spellings are also frequently used, especially in Britain. While Leslie may not be the freshest name in the bunch, it's become a modern classic and is one of the surprising names always to have ranked among the US Top 1000 for girls.

Liam is the top boys' name in the US, holding the Number 1 spot for the past seven years and also ranking as one of the most popular boys' names around the western world.

The capital of England makes a solid and attractive twenty-first-century choice in the US where it is currently in the Top 1000. Given to nearly 1000 girls and 200 boys each year, it is a unisex option that has been in slow decline since its peak in 2013. Conjuring up images of Big Ben, red phone boxes, and the London Eye for some, but perhaps the rush hour commute and grey skies for others, London is far less popular in the UK and other English-speaking countries.

Lori, with this sleek modern spelling, was an extremely popular name in the middle of the 20th century, ranking among the Top 100 girls' names from the early 1950s until the early 1980s.

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.

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.

Britney Spears' little sister Jamie Lynn was one of the first to put this nickname on the birth certificate. Cute for a child, but we recommend giving her the option of the full name for later use.

As a highly popular girls’ name in all Spanish-speaking countries, this saintly Latin variation of Mary retains a timeless beauty. Through the centuries, Maria remains one of the most widely-used girl names starting with M.

For a name that was in the Top 20 for a whole decade – the 1930's – Marilyn has attained the status of almost a one-person name. Just say the name Marilyn, and most people will know who you mean. Yet strangely enough, though Marilyn Monroe (born Norma Jean and renamed in tribute to earlier star Marilyn Miller) was the sex symbol of her generation, very little stardust adhered to her name. In fact, when Mariah Carey wished to honor the star in her daughter's name, she chose to call her Monroe rather than Marilyn.

Fun fact: Marion was the birth name of movie star John Wayne. Although commonly thought of as a female name today, it was actually more popular for boys until the late 19th century, and was given to roughly equal numbers of boys and girls throughout the 1970s-2000s.

Mark has the rare appeal of a strong, sleek name with a minimalist modern feel and ancient roots. The name Mark is taken from the Roman god of war Mars, also the namesake of the planet.

The name of our first First Lady still has something of a prim and proper image, academic and efficient. That quiet, traditional, and tasteful gestalt is exactly what makes Martha appealing to some parents today.

Though it's close to the German and French form of Matthew, Mathis, this name of the great artist can work as well for girls.

In the USA, Maurice was in the Top 200 for most of the 20th century; since 1990, however, it has been on a slow and steady decline. This name has the potential for some old-school cute nicknames such as Mo as well as the more trendy Reece.

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.
