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.

This jaunty Celtic surname -- the most common family name in both Ireland and the US -- is totally viable as a first. The arguably most famous Murphy is TV's Murphy Brown, and indeed the name is twice as common for baby girls as for baby boys today. But still, it's solidly gender neutral and works equally well for all sexes.

Harley is a tough guy, while the rhyming Marley has a softer, gentler image. The name brings to mind reggae great Bob Marley, as well as the lovable dog from bestseller Marley and Me.

Reggae master Bob's surname was one of the biggest risers on the popularity charts for girls in 2008, with spellings Marlee and Marely also leaping in favor. Also used for boys, Marley is one of the top unisex names in the US.

Marguerite is a classic French name with a remnant of old-fashioned Gallic charm; and is also a variety of daisy. Chic again in Paris, it's definitely ripe for revival here.

Originally a nickname for someone who loved to sing or whistle, Merle is sleek but gentle, with a hint of great grandpa about it..

Morris is as quiet and comfortable as a Morris chair, and has the same vintage feel. Once a Top 100 name in the early 1900s, Morris fell completely off the roster in 1995, probably due to lingering fallout from his identification with Morris the cat's ("the world's most finicky cat") 9 Lives cat food commercials.

Monroe is a presidential surname which feels fresher than Jackson, Lincoln and Taylor. Marilyn Monroe is a famous female namesake, but her smart Scottish surname feels equally usable for either sex. Plus, we think old man nickname Moe would sound both cool and adorable on a baby boy today!

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.

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.

Simple and universal, Marco is a Latin classic that would make a much livelier namesake for an Uncle Mark. It was used for her son by actress Jill Hennessy and goes well with surnames of any nationality.

Mitzi is a sparky German nickname name that might appeal to parents drawn to the genre of lively vintage girl names that proliferated in 1930's musicals.

Once a poetic Celtic name, that of the angel who governs the month of June, Muriel has for a time, become the mom or grandma of TV sitcoms. A Top 200 name from 1912 to 1933, Muriel might just be due for a comeback, fitting as it does with the likes of Margot, Mabel, Marjorie, and Marilyn.

Adventurous parents are starting to look back to names of ancient gods like Mercury, Zeus, and Apollo. This one is also a planet and a metallic element, and has a friendly nickname, Merc. The Roman god Mercury, which derives from the Latin words for trade or wages, is the patron of tradesmen and travelers and the fastest-moving planet in the solar system. Mercury is the planet associated with the sign of Virgo, so this is one of the prime names for Virgo babies.

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.

Monte, pronounced with two syllables as brother Monty, is an old-fashioned nickname-name that's reclaiming a certain amount of dash and charm. It was recently chosen by actor Guy Pearce--which may signal a comeback.
