Just the kind of casual, flippant nickname that upscale Brits are putting on their sons' birth certificates, but few U.S. parents are.

Allen is the spelling of this name -- other common spellings are Alan and Allan -- most associated with the surname; it might also be the most appropriate if you're trying to steer clear of Al as a nickname, as this can easily offer you Len or Lenny as options.

Most Bills today are dads...or grandpas. The younger Williams are usually nicknamed Will, or called by their full names.

Marvin has been neglected for so long that it's hard to believe that it has windswept Welsh roots. It also has some strong namesakes going for it -- singer Marvin Gaye, composer Marvin Hamlisch and boxer Marvin Hagler. It's the real name of both Neil Simon and Meatloaf. And let's not forget mention Marvin Gardens on Monopoly.

Actor Joaquin Phoenix (brother of River, Rain, Liberty and Summer) highlighted this one, then Kelly Ripa began talking about younger son Joaquin on her daily TV show, and presto—it's now one of the hottest and most appealing multicultural baby boy names.

Murray, you may be surprised to discover, is a Scottish surname name --that of an ancient noble clan--with a sea-swept meaning, and just could be in the next wave of reevaluated grandpa names. Currently Number 60 for baby boys born in its native Scotland; it was at its highest in the US in 1922, when it reached Number 208, but has been off the list since 1975. Could it be time for a comeback?

Glenn appealed to a lot of post-World War II parents for its cool, leafy image, also calling up the Big Band sounds of Glenn Miller and the calm, composed image of actor Glenn Ford, whose name at birth was the Welsh Gwyllyn. It could possible be in line for a comeback in the more nature-evoking spelling of Glen, as used by Glen Campbell, or possibly even the Welsh Glyn.

This lilting Irish saint's name shone in neon lights on Broadway for the classical 1947 musical "Finian's Rainbow," later made into a film starring Fred Astaire as Finian McLonergan, and there was also a character on "General Hospital" named Finian O'Toole. With the growing popularity of Finn and Finlay/Finley--and boys' names ending in 'an'--Finian, which can also be spelled Finnian, seems like a sure-fire winner.

Just like Sam and Ben, Tom could be revived as a simple, well liked name on its own. Tom, just Tom, is one of the Top 100 Boy Names in France

Still one of the most appealing short forms, which goes a long way toward explaining the sustained popularity of Matthew. Matt is perennially the popular guy in high school, friendly, attractive, and comfortable with a baseball. Matty or Mattie are cute for a younger boy.

This Americanized spelling of the Dutch name is now used nearly exclusively for girls in the US.

Eliott is a masculine name representing a variation of Elliott, which originated as an English surname derived from the Hebrew name Elijah, meaning 'my God is Jehovah' or 'the Lord is my God.' This specific spelling with one 't' is less common than the double-t version, giving it a slightly more distinctive appearance while maintaining the familiar sound. Eliott combines traditional roots with a clean, modern feel. The name has seen steady usage throughout English-speaking countries, experiencing an uptick in popularity during the early 21st century as part of the trend toward classic names. It offers the friendly nicknames Eli or El. Eliott carries an intellectual, approachable quality that works well from childhood through adulthood.

Garry is a masculine name typically considered a variant spelling of Gary, which originated as a diminutive of names like Gareth or Gerald, or from the Germanic element "gar" meaning "spear." This alternative spelling with the double 'r' was particularly popular in the mid-20th century. Garry peaked in popularity during the 1950s and 1960s alongside Gary, associated with celebrities like actor Garry Cooper and musician Garry Moore. The name has a friendly, approachable quality while maintaining masculine strength. Though less common than the single-r spelling, Garry offers a slightly distinctive alternative to the more standard form. Its usage has declined since its mid-century peak, now giving it a somewhat vintage character that connects to mid-century American culture.
