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.

Aveline is a name that's long been an obscure cousin of more widely-used choices, but may come into its own riding the tail of the megapopular Ava, which may derive from the same root.

Though it may not be as sweet and gentle as, say, Violet, the purple-hued Hyacinth still might hold some appeal for the parent seeking a truly unusual flower name.

The Scottish Eileen was a midcentury darling that was on a long downward slide for decades. And then, in 2012, it took an unexpected pivot and has been inching upward in the US. The unrelated but similar-sounding Isla may have revived the taste for Eileen. Isla along with Lee and Lena might be nicknames for Eileen. Eileen is an Anglicized form of the Gaelic Eibhlin or Aibhilin, which is technically a form of to Evelyn/Aveline, but is also sometimes considered part of the Helen family of names. Aileen is the Irish version, less popular now than Eileen.

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.

Monroe is a presidential name which, thanks to the immortal beauty of Marilyn Monroe, is catching on fast for baby girls. Mariah Carey and Nick Cannon chose it for their twin daughter, honoring Marilyn Monroe. Their use of Monroe as a girls’ name did much to revive this Old Man name, a la Sydney, as a newly fashionable choice for girls.

Well-established Irish and Scottish name that has never really caught on across the pond. Remembered by an older generation as the beautiful red-haired ballerina in the film The Red Shoes, Moira Shearer.

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.

This surname name popularized for girls by TV's Murphy Brown back in the 80's and 90's still has some breezy energy. Almost 400 baby girls were named Murphy in 2021, versus just over 200 baby boys, making the name solidly gender neutral.

Mari enjoyed some mid-century popularity as a nicknameish version of Mary, but now deserves a second look as a multicultural classic. Popular in Norway and Armenia as a variation of Marie, it is also the name of a Basque goddess and an Estonian word name.

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.

Wade has never been outside the US Top 1000 for boys - there's a reason for that. It has a clean spelling, fresh sound and is neither too trendy (unlike Kade or Cade) or too old-school (like Richard or Albert). We think Wade is a winning name.

Boys' favorite retains more of its poetic, windswept quality when used for a girl, as Robin Wright and Sean Penn did. Alyssa Milano gave her daughter Elizabella Dylan as a middle name.

Zaire was a Central African state from 1971 to 1997 that has recently risen up the charts as a boys name. Deriving from a Congo term meaning "the river that swallows all rivers", it makes a bold and wearable choice for a son.

Mirren is a lively and attractive Scottish name, popular in its native country but best known outside Scotland as the surname of the English actor Dame Helen Mirren. It is thought to be a Scottish derivative of the name Marion, from Mary.

Most of the notable Rivers have been male, but this nature name certainly flows as well for a girl. The name River is still rising for both genders, with about 3500 baby boys receiving the name last year vs. 1900 baby girls.

Nature names like Ocean and River are flowing back into favor, especially with nature lovers and green-oriented parents. In 2024, it was given to 483 boys and 325 girls, making this a unisex favorite in the US, while in the UK, it is considerably more popular for girls.

Marian's (and sister spelling Marion's) image has gone through a sea change of late, recalling less middle-aged matron and more Robin Hood's romantic Maid Marian. Some influences: the SJ Parker-M. Broderick twin daughter Marion and the glamorous French actress Marion Cotillard.

Water names are a cool category these days, and this one of the famous Egyptian river is no exception. It streamlines the fussier Niles and also may be thought of as a color name, meaning dark blue or indigo.

An offbeat possible replacement for the overused Melissa and Marisa, Nerissa was used by Shakespeare for Portia's witty confidante in The Merchant of Venice. Queen Elizabeth has a cousin named Nerissa.
