Jack may have fallen from its Number 1 place in England, but in the US it's as popular as it was at its height in the 1920s and 1930s. A durable, cheery, everyman form of John, Jack ranks as one of the most popular boy names starting with J.

Ezra has a lot going for it: the strength of its heroic Biblical legacy, its quirky sound, and its fresh but familiar feel. Ezra is now at its highest point ever, but its intuitive streamlined spelling and deep roots could make it a worth successor to Elijah in the Top 10 -- or even to Liam or Noah at Number 1.

Imogen has long been fashionable in England and is gaining favor in the US among stylish parents. Pronounced the British way — the initial i is short as in Kim, as is the final E as in Ken — Imogen is as pretty and classy as it is distinctive.

Clara is a strong, lovely girls' name that's always ranked among the US Top 1000 girl names but has been climbing since the turn of this century. It now ranks right at Number 78, making it a modern classic that's neither too popular nor unfamiliar.

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.

Declan is the Anglicized form of the Irish name Deaglán. St. Declan was one of the first missionaries to bring Christianity to Ireland, preceding St. Patrick. Originally from Wales, he founded the monastery of Ardmore in Ireland.

Vibrant, sassy, and bubbly, Ruby is a vintage gem that hasn't lost any of its sparkle. Currently popular in a number of English-speaking countries, Ruby is proof of the 100 Year Rule, trending again for the first time since its heyday in the 1910s.

Ella is a sweet, simple name that owes much of its current popularity to the popularity of other names, from Emma to Bella to Emily to Ellie.

A beautiful modern Cornish nature name that is rapidly picking up steam in the States: even spawning variant spellings like Elowyn and Elowynn. In its native region, it wasn't widely used as a name before the twentieth century, when the Cornish language was revived. A fresh and magical member of the fashionable El- family of names, it has a pleasant, evocative sound.

Simon is pure and simple (not in the nursery rhyme sense), and an appealingly genuine Old and New Testament name that's not overused. These factors make Simon a stylish yet classic choice.

Stella is a name with star quality and sparkle, that manages to sound both ethereal and earthy. Celestial but not otherworldly, it lands somewhere between the popular Ella and bold Seraphina.

Charlotte, the name of the young Princess of Cambridge, is the latest classic name to join Sophia, Emma, Olivia, and Isabella at the top of the popularity list. It is now among the most popular girl names in many English-speaking and European countries.

Like the French author with whom the name is most closely associated, Colette is a chic and charming name, sharp, stylish, and feminine but without the frills of Nicolette. After disappearing from the charts for 30 years, Colette rejoined the US Top 1000 back in 2012 and is still on the rise.

Olivia, a lovely Shakespearean name with an admirable balance of strength and femininity, is the Number 1 name for baby girls in the US and one of the top girls' names around the world.

Liam is the top boys' name in the US, holding the Number One spot for the past eight years and also ranking as one of the most popular boys' names around the western world.

William is one of the most enduring of classic names for boys. It's also among the most popular boys' names, as American parents see it as being ideally conservative yet contemporary, and hands-down the most popular baby name beginning with W of all time.

Owen, a resonant Celtic name, has ranked among the Top 100 boys' names in the US for 20 years and is now at its highest point ever.

Audrey is one of the girls' names that have been rising due to their connection to Old Hollywood glamour — in this case the eternally chic and radiant Audrey Hepburn. Audrey has another very different appeal as one of the elite group of girl names that mean strong, brave, or powerful.
