Morgan has long been a traditional Welsh male name, a variant of the Old Welsh name Morcant, from the Welsh elements mor, meaning "sea" and cant, "circle." The female Morgan is unrelated to the male version—it is a name from Arthurian legend created for Morgan le Fay, King Arthur's half-sister and famed sorceress. Her name comes from Morgen, an Old Welsh name meaning "sea-born," and is related to the Irish name Muirgen.

Manon is an endearing French pet name for Marie or Marianne; it has the international yet straightforward feel that makes it a viable import. Manon of the Spring was a gorgeous French film, Manon Lescaut a 1731 novel by Abbe Prevost, set in France and Louisiana, that was controversial in its day. It formed the basis of operas by Puccini and Massenet, and several films and TV series.

Bright and vivid, Marisol is a sunny name of Spanish origin and an excellent candidate to cross languages, a la Soledad, Paz, and Solana. Familiar in its native Spain (though no longer a top choice), a recent year also saw Marisol make the Top 1000 in the US, the Top 200 in Italy, and the Top 100 in Mexico.

Michelle is the feminine form of Michel, the French variation of Michael. Michael was derived from the Hebrew name Mihka’el, meaning "who is like God." The alternate spelling Michele, with one "L," was the original version of the name. Michelle appeared as a later Anglicization in the 20th century.

Mara is the evocative ancient root of Mary, appearing in the Book of Ruth, in which Naomi, devastated after the death of her two sons, says "Call me not Naomi, call me Mara." It's one of the girl names starting with M that both fits in and stands out.

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.

Mariana is that unusual name that is more than the sum of its parts. While Mary or Maria and Ana or Anna are both perfectly nice classic names, Mariana achieves a lyrical elegance that transcends them.

Margo and Margot sound exactly the same, so why has the Margot spelling hopped back onto the Top 1000, outpacing Margo in numbers more than two to one? (Over 350 baby girls were named Margot in the most recent year, versus 150 named Margo.)

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.

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.

Maggie is a cute, earthy short form that has been in style for several decades now, still sometimes used as an independent name by such parents as Jon Stewart. First used in Scotland, it got a large bump in popularity via the 1971 Rod Stewart hit song "Maggie May." Today's Maggie might just as well be short for a more adventurous name such as Magdalena or Magnolia as for the classic Margaret.

Maggie Gyllenhaal was born Margaret.

An underused classic that has proved surprisingly unisex over the last few decades, being given to roughly the same number of baby girls and boys in the US from the 1970s to the 2000s. For a girl, Marion has a sturdy old-fashioned charm.

Capturing some of the playful elegance of Madeleine, while avoiding any confusion over the end sound, Madelyn is now an established spelling variation of the French classic. Sweet but strong, Madelyn is a versatile choice that lends itself to the almost inevitable nickname Maddy.

Magdalena is a pretty name forever associated with the fallen-yet-redeemed Mary Magdalen; often heard in the Hispanic community. But forward thinking parents are reviving Magdalena along with Magdalene and the unrelated but similar-sounding Marguerite.

Lilting and nearly unknown here, with the currently popular ella ending, makes a good Marissa alternative.

As with many grandmother-y names, this choice may be coming back into style.

Maia was derived from the Greek word maia, meaning "mother." In Greek legend, she was the fair-haired daughter of Atlas who mothered Zeus's favorite illegitimate son, Hermes. To the Romans, Maia was the incarnation of the earth mother and goddess of spring, after whom they named the month of May. Maya is the more common spelling.

Maple is one of those sweet-spot word names that sounds so almost name-like that it doesn't feel outlandish or strange, despite its relative newness as a given name. Just as Juniper is adjacent to June or Pippa, Clover like Chloe or Clara and Ember like Emma or Ebba, Maple is enough like Mabel, Maisie and Mae that it blends in well and has a touch of borrowed vintage charm.

This popular name in various Slavic countries and in Italy holds considerable continental appeal. It is the full name of Ukranian-born actress Mila Kunis, noted for her award-winning role in the film Black Swan. Another actress bearing the name is Milena Govitch, of Law & Order.

A melodious choice big in the 60s, Melody is now starting to pick up tempo again. It cracked the Top 100 for the first time ever in 2024. Melody is also the name of Ariel's equally curious and more tomboyish daughter in The Little Mermaid sequel. Read more about Melody and other Disney Princess Names in our featured blog.
