Rugged but gentle, Rhys is the traditional Welsh spelling of this name, which can also be anglicized as Reese or Reece. Up until 2010, Reese was the preferred spelling in the US, perhaps because parents were concerned about mispronunciation. However, Rhys has since taken over for boys and is now used twice as often as Reese.

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.

Mae, a sweet and springlike old-fashioned name, hadn't been on the national charts in forty years, but finally made it back in 2010. Mae is derived from May, the month name that was chosen for its connection to Maia, the Roman goddess of growth and motherhood.

Beau suggests someone devilishly handsome, with a large measure of southern charm—a nice image to bestow on your boy. Often solely a nickname in the past, it's now standing firmly on its own. Beau has been on the Social Security list non-stop since 1969.

Simple, classic, strong, and versatile, Jane has shrugged off her plain associations to become a short, punchy name with plenty of literary significance. Calling to mind Jane Austen and Jane Eyre, this charming choice is in the Top 300 in the US and The Netherlands, but a currently underused option elsewhere.

Max was derived from Maximilian, a Latin name that originated from the Roman family name Maximus. The character name Max in the children's classic Where the Wild Things Are had an impact on baby namers. Max is a widely used name internationally.

June, a sweetly old-fashioned month name derived from the goddess Juno, was long locked in a time capsule with June Allyson (born Ella) and June Cleaver, but is rising again especially as a middle name.

Kit is a crisp, old-time nickname with plenty of spirit and style. In the UK it's a rising star for boys, while in the US, it is trending upwards for girls too.

Gus is a homey grandpa nickname name that can work as a short form for any of the above or stand on its own as a cutting-edge replacement for Max and Jake--though it was off the Top 1000 from 1978 until 2016, when it squeaked in at Number 999.

The Reid spelling is the most popular by half, probably because it feels more like a name than Reed, which looks more like a word. It's used occasionally for girls but this name is firmly in the boys' camp.

Rugged and outdoorsy, Heath was an obscure choice until the 1960s when it was used in the television series, The Big Valley for character Heath Barkley. It peaked in the 70s when it reached the US Top 200, but it has since fallen to the latter end of the Top 1000.

Strong and modern, Cade shot up the popularity lists around the millennium—it was as high as Number 201 in 2001. Now, it has declined in popularity slightly, but nevertheless remains in the US Top 300, given to around 1200 babies each year. Combined with all the baby Kades, Cadens, Kaidens and Kaydens however, it might feel even more popular that it actually is.

Rue has gone from Golden Girls actress to Hunger Games heroine to a fresh alternative to beloved middle name Rose. This botanical name is also a coincidental double word name, meaning "regret" in English and "street" in French. Despite these unfortunate secondary meanings, Rue has real potential to be one of the most popular new middle names for girls.

One of those simple, straightforward English surnames -- and with a presidential pedigree -- that's easy to translate into a first. Chosen by both Kevin Costner and Jessica Alba for their sons, it has been climbing the US charts since 2009.

A top ranking choice in England and Wales, making frequent appearances on the Telegraph Announcments, Rafe feels equal parts rugged, amiable, and posh. Traditionally seen used a variant of Ralph (itself from the Old Norse Ráðúlfr), it came into use in the 17th century to reflect this particular pronunciation.

Patrician to the core, Hugh was firmly in the Top 100 until 1903. It's never achieved those heights again, though it has always managed to remain in the Top 1000, scraping bottom at literally Number 1000 in 2006 before reversing course and heading back upwards.

Rhett has been more tied to Gone with the Wind than even Scarlett, but now we're hearing rumblings of its finding new and independent favor among parents, perhaps emboldened by the growing popularity of Scarlett.

Hank is a midcentury guy nickname (which actually dates back to the seventeenth century) of the Al/Hal/Dick school, which has been on recess from the playground for decades. Now it's just beginning to be given on its own again, appreciated for its earthy, sportsguy cool. Hanks Aaron and Greenberg (born Henry) and Hank Williams (born Hiram) Sr and Jr. are worthy namesakes.

The name of the sainted mother of the Virgin Mary was among the top girls’ names for centuries, in both the original English Ann spelling and the French Anne. Both left the Top 100 around 1970 but Anne is still among the most classic names for girls, although others are more likely to choose the original Hannah, the Anna variation, or even Annabel or Annabella.
