With its cool -X ending, Jax is an update on the classic nickname Jack, likely inspired by the rise of Jackson. It garnered attention in the US thanks to the game, Mortal Kombat II back in the '90s, and was pushed up the charts when it was used in the show Sons of Anarchy, in which Jackson "Jax" Teller is the central character.

Cute but cool, fresh but familiar, Ozzy was one of the fastest-rising boy names of 2021 and has continued to rise in the US and the UK ever since. While hard-core rocker Ozzy Osbourne might not be everyone's idea of a role model, his nickname name, along with others like it (think Iggy, Ziggy and Izzy) are forging their own way up the charts.

Bear has suddenly lumbered onto the baby name landscape. Perhaps inspired by British adventurer Bear Grylls (born Edward Michael), first celebrity chef Jamie Oliver used it as the middle name for his boy Buddy, and Alicia Silverstone called her son Bear Blu, followed by Kate Winslet's Bear Blaize.

Ryder, one of the current favorite er-ending boys’ names, has been in the spotlight since Kate Hudson and her rocker husband Chris Robinson chose it for their son in 2004. Very popular in several provinces of Canada, Ryder was chosen by John Leguzamo for his son and adorns Boy Meets World star Ryder Strong.

Annabel is a spirited name that embodies quirky British gentility. Appearing in Scotland as early as the twelfth century, where it was a royal name, it also recalls the romantic Edgar Allan Poe poem Annabel Lee, written upon the death of his young wife, Virginia.

The girls have Violet and Scarlet and Ruby and Rose, but for the boys there's a much more limited palette of color names. Grey/Gray is one exception, which could make for a soft and evocative—if slightly somber—choice, especially in the middle. Kaitlin Olson and Rob McElhenney named their son Leo Grey.

The graceful, natural image of the verdant shade tree transcends any connection with President Johnson.

Indie is an independent-sounding nickname name that is in the Top 100 in Wales. As a diminutive, it's growing in popularity -- along with indie films, indie publishing -- and the reason some parents are choosing names like India and Indigo. The Indie version seems more feminine, while Indy as in Indiana Jones tends toward the boyish.

It's a long time now since this casual but suave name was linked to velvet-throated, cardigan-sweatered singer Perry (born Pierino, son of Pietro) Como's day... and this could be the moment for a reassessment. Other Perry associations are designer Ellis and the fictional Perry Mason and Perry White. There is also the option of taking the long way round to Perry via the more substantial Peregrine or Percival.

The doe-eyed Fawn is as gentle and soft as the baby deer it represents. And much like that baby deer, it carries with it the potential of new life. Fawn was featured at the bottom of the Top 1000 throughout the '60s and '70s — around the same time that Bambi came into play. But unlike Bambi, Fawn maintains relevance in the 21st century, thanks to its warmth and ties to the natural world. We would love to meet more baby girls named Fawn.

Botanical choice that can work for either gender. Simple and straightforward. Caveats: rue means "regret" in English, and "street" in French. Now in the Top 1000 in England and Wales for girls and trending upwards in the US, it is nevertheless still given to a handful of boys each year. It could equally work as a nickname for a Ruben, Rudy, or a Rupert.

A multicultural name, that's currently on style and fits right in with Kaia, Maya, Raya, and Mia. Currently in the Top 500 in both the UK and The Netherlands, it has several different origins and meanings.

Could Lilac be the next Lila or Lily or Violet? It certainly has a lot going for it--those lilting double 'l's, the fabulous fragrance it exudes, and the fact that it's a color name as well, providing a ready made nursery theme. In addition, the lilac is symbolic of first love.

A glamorous surname name most famously borne by 1930s icon Jean Harlow (born Harlean Carpenter), Harlow is also the name of a town in the English county of Essex. Outside of the UK, Harlow would fit right in with contemporaries Arlo and Marlow(e).

Aspen is part of two groups of stylish and unique baby names: nature names and place-names. The name of a graceful tree in the poplar family with heart-shaped leaves so delicate they quiver in the gentlest breeze, Aspen is also the name of a trendy Colorado ski resort. Aspen started as a unisex name possibility but now is much more frequently worn by girls.

This twist on the popular Everett takes it to lofty heights and gives it a geographical and nature-inspired link. The snow-capped Everest could make a name that stands out without feeling too out there, and it may be seen more often in the classroom (that is, outside of the textbooks) in coming years.

Down-home nickname name once associated with the friendly dragon on kids' TV. As Oliver rises, we may well hear more Ollies.

The original Kyle has sparked many variations, including Kylie, Kyler, and Kylo, after Kylo Ren, the villain played by Adam Driver in the seventh Star Wars movie, released in December 2015.

Liv combines the succinct charm of a nickname—people might assume it's short for Olivia—with the solidity of being a classic stand-alone Scandinavian name with a life-force meaning. It was brought into the public eye (in the English speaking world that is) due to the fame of actress and Aerosmith daughter Liv Tyler.

Merritt is an old-style surname name that could be seen as a positive virtue name. It was used in the late 19th and early 20th century for boys, reaching the Top 400 in 1899, and is notable today for being one of the names most evenly divided between boys and girls. Emmy winner Merritt Wever helped popularize it for girls.
