The oldest-known form of Mary, serious and solemn Miriam has been a particular favorite of observant Jewish parents. But we can see it extending beyond that sphere into the next wave of Old Testament names post-Rachel, Rebecca, Sarah, Hannah, and Leah. Miriam is currently the Number 1 girls' name in Israel.

Thanks to Mariah Carey, everyone now knows this name – and is aware that Mariah's pronounced with a long i – just as Maria was in the Jane Austen era. And though Mariah now sounds modern, it was heard as far back as 1550 in Great Britain.

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

This pretty sea-born name was used to dramatic effect by Shakespeare in his play Pericles for the virtuous princess who says she is "Call'd Marina, for I was born at sea."

Retro short form of Marina, now dated to the era of the Hitchcock movie that made it famous. In the UK, it's one of the hottest vintage names of the moment, perhaps inspired by British singer Lily Allen, who gave it to her second daughter in 2013. It's also a character name on the hit TV show Girls.

Sleek and stylish with a touch of quirkiness about it too, Maxine is a popular choice in Belgium and France, and has been climbing up the US charts too. Following a two decade absence, it re-entered the Top 1000 in 2016 and a recent year saw it rank just outside the Top 500.

Maude, also spelled Maud, is a lacy, mauve-tinted name that was wildly popular a hundred years ago, but has been rarely heard in the past fifty. Some stylish parents are starting to choose it again, especially as a middle.

Minerva is the long-neglected name of the Roman goddess of wisdom and invention, the arts and martial strength, one of the mythology names for girls that might appeal to adventurous feminist parents. With Juno and Jupiter, she made the Capitoline triad, whose worship was at the very center of Roman religion.

Megan originally evolved from Meg, which itself derived as a nickname for Margaret. Margaret ultimately comes from the Greek word margarites, meaning "pearl." Megan is no longer a common nickname for Margaret—it is most often used as a full name. Other spellings include Meghan, Meagan, Megyn, and Meaghan.

Melissa derives from the Greek word mélissa, meaning "bee," which was taken from the word for honey, meli. In Greek mythology, Melissa was a nymph who nursed the infant god Zeus with honey. Melissa was used as a given name by the early Greeks, as well as for fairies by Italian Renaissance poets.

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.

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.

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.
