Middle Names: Boys

When actress Rachel Griffiths chose this highly unusual name for her son, many assumed it was a bizarre invention. But a noted Australian poet (Griffiths is an Aussie) is known by this name.

With the popular 'ash' sound and a contemporary feel, Cash is a widely used name in the US. Used occasionally before the 2000s, Cash really took off in 2003, following the death of American musical legend, Johnny Cash.

Finn is a name with enormous energy and charm, that of the greatest hero of Irish mythology, Finn MacCool (aka Fionn mac Cuumhaill), an intrepid warrior with mystical supernatural powers, noted as well for his wisdom and generosity.

If you like the Finn names and love James Joyce, Finnegan is extremely winning. Will & Grace 's Eric McCormack chose the Finnigan spelling for his son. And of course Finnegan gains you access to the great short form Finn.

Finnigan is another way to spell Finnegan, one of the energetic Irish surname-names in vogue now. One note: While Finnigan, Finnian, Finley and so on are appealing names on their own, you don't need to use a longer form to get to Finn, which is a perfectly proper name all on its own.

Fox is one animal name backed by a longish tradition, and then popularized via the lead character Fox Mulder on X Files. Fox is simple, sleek, and a little bit wild, and could make an interesting middle name.

A possible hero name inspired by notables from Spanish poet/playwright Federico Garcia Lorca to writer Gabriel Garcia Marquez to the Grateful Dead's Jerry Garcia.

Harrison, a name made viable by Harrison Ford, is increasingly popular with parents who want an H name that's more formal than Harry or Hank but doesn't veer into the stiff Huntington-Harrington territory.

Hendrix is one of those hip rock and roll names, like Lennon, Jagger and Presley, that have been used by fellow celebs and others, to honor the seminal guitarist/singer/songwriter Jimi. And this one has the trendy 'x' ending, as well, helping to propel it up the charts and into the spotlight.

Hunter has been dropping a bit for the past few years but is still one of the leaders of a distinctive band of boys' names that combines macho imagery (Hunter, Austin, Harley) with a softened masculinity. Hunter was for years attached to gonzo journalist Hunter S. Thompson; Josh Holloway used it for his son.

Jackson is one of those names that's much more popular than you think, coming in near the top of our annual Playground Analysis, which ranks names by grouping all their spellings together. Last year, nearly 17,000 baby boys were named Jackson -- along Jaxon, Jaxson, Jaxxon, Jaxen, Jaxyn, Jaxsen, and Jaxsyn -- which counted together makes it the Number 3 boys' name.

This is a strong new James varietal, sometimes shared by girls. An original way to honor Grandpa Jim, Jameson is swiftly moving up the charts, entering the Top 100 for the first time ever in 2017. Jameson is one of the hottest boy names starting with J, still the most popular first initial for boys' names. One small caveat: Jameson is also a brand of whiskey.

John reigned as the most popular of all boys' Christian names for 400 years, from the time the first Crusaders carried it back to Britain until the 1950s. Then American baby namers finally seemed to tire of this straight-arrow, almost anonymous John Doe of names, replacing it with fancier forms like Jonathan and the imported Sean and Ian.

Jonah, the name of the Old Testament prophet who was swallowed by the whale, only to emerge unharmed three days later, is increasingly appreciated by parents looking for a biblical name less common than Jacob or Joshua, yet not too obscure. Plus, Jonah comes with a ready-made nursery-decorating motif.

Used as a first name for a handful of girls every year, Joplin could be seen as a distant cousin of other -lin names, like Caitlin, Brooklyn and Braelynn. We think it works even better as a musical middle name possibility for fans of Janis... or Scott. Both great connections — albeit very different from one another.

Jude is a modern star, maintaining a steady level of popularity -- but not TOO much popularity -- for more than a decade now. Thank Jude Law and the great Lennon-McCartney song "Hey Jude", double-handedly responsible for propelling Jude up the charts.

Chosen for their first son by musical couple Gwen Stefani and Gavin Rossdale, this Jamaican place and elegant British surname also boasts the more regal yet user-friendly short form, King.

Mason is an occupational surname that ranked among the Top 10 name for boys throughout the 2010s, after its choice as one of the first Kardashian baby names.

Miles, which has a permanent veneer of cool thanks to jazz great Miles Davis, is a confident and polished boys' name that's an American classic. Always ranking in the US Top 1000, it's been drifting up the charts for the past half century but has never been TOO popular.
