Boys

Once a powerful Roman clan name, Cecil has lost much of its potency over the years, though it retains a strong presence in the sports and jazz worlds. Past bearers include film giant Cecil B. DeMille, poet Cecil Day Lewis, father of Daniel, and photographer Cecil Beaton. Fictional Cecils appear in Oscar Wilde's play, Lady Windemere's Fan, E. M. Foster's A Room With a View and the film Lee Daniel's The Butler.

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.

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.

Luke is a cool-yet-strong Biblical name with a relaxed cowboy feel, which has been on the rise since the advent of Luke Skywalker.

Mitchell has had something of a roller coaster ride, showing some panache in the forties and fifties, when it was seen as a sharper alternative to Michael with its cool Mitch nickname, slipping a bit, then resurfacing in the 90s when it reached as high as Number 71. Mitchell Pritchett is one of the leading characters on the TV sitcom Modern Family.

Nathaniel was derived from the Hebrew name Netan’el, meaning "gift of God," composed of the elements natan, meaning "to give," and ’el, in reference to God. The name is featured several times in the Old and New Testaments, typically spelled Nathanael. In the New Testament, Nathanael is also known by his other name, Bartholomew.

Niall is pronounced nye-al--something like Neil, but this Irish spelling of the name makes it much more current and cool.

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

Raphael is a romantic archangel name that sounds both artistic and powerful. Raphael is also a great cross-cultural choice, with significance for people with both Latinate and Jewish roots, plus plenty of grounding in the English-speaking world.

Sebastian is an ancient martyr's name turned literary, and Little Mermaid hero—think Sebastian the Crab—that's more popular than ever, as a classic-yet-unconventional compatriot for fellow British favorites T Theodore and Oliver.

See the popularity graph below for the name Theo? It's been heading straight uphill since 2010, when it hopped back onto the Top 1000 after a 60+ year absence.

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.
