Isla is a hit name throughout the English-speaking world but hasn't found the same popularity in other western countries, perhaps because its spelling and pronunciation don't make sense for those whose native language is not English. Think island without the final two letters.

Penelope is an unlikely 21st century baby name success story. Off the Top 1000 for 25 years, Penelope jumped back on in 2001 and has been heading uphill ever since, propelled by the trend for mythological names, Spanish actress Penelope Cruz, and some high-profile celebrity babies.

Lila is one of the girl names with a double l sound — Lila, Lola, Layla, Leila, Lily et al — that have caught on in a major way., Delicate yet dynamic, Lila has a slightly international flair.

A strong, grounded choice that still has plenty of energy and charm, Leona is the feminine form of Leon, itself derived from the Greek word for "lion". Associated with courage, leadership, and royalty — and the star sign of July and August — Leona is popular in Croatia and Sweden, but familiar across the US, the UK, and continental Europe.

A lovely (and uncommon) longer form for Nora, one of the most fashionable international nickname names around. Lenora fell off the US charts in the 70s, but just re-entered in 2022 as parents' love for short forms Leni and Nora is growing.

Marin is a lovely county north of San Francisco, and a lovely baby name on the rise, one which sounds more refreshing than the more familiar Marina.

As Meghan/Megan and Reagan/Regan show signs of wilting, along comes Teagan to take up the slack: definitely one to consider. The vast majority of American babies named Teagan are now girls. A variant spelling is Teaghan.

Scottish Marjorie and her English twin Margery were early twentieth century favorites that date back to medieval times, when it was popular among the royals. They were at their height in the 1920s, when they were seen as more lively versions of the old standard. Marjorie was always the preferred spelling, in the Top 25 from 1920 to 1927.

Light, pretty and distinctive in appearance, Carys is one of that sweet group of girl names with a loving meaning. A relatively modern name, it didn't come into use in its native Wales until the late nineteenth century, and even then, it wasn't a mainstream choice until the middle of the twentieth century. Pronounced as CA-riss, the beginning sound is like the one cat or Catherine, not said to rhyme with Claire.

Briony may be the variation and Bryony the original, but many parents will see this as the more authentic-feeling version of this attractive botanical name. Melodic and bright, it was once a Top 400 name in the UK back in the 90s but has since fallen out of favor, as has Bryony.

Time was, even C-starting Catherines who called themselves Kate spelled it with a K, but Cate Blanchett changed all. Cate is now as acceptable as (but not as well used as) Kate. Cait might be short for Caitlin.
