Llewellyn/Llywelyn is a common patriotic first name in Wales, with its distinctive Welsh double LL's; in the U.S. Llewellyn would make a daring choice, though with the chance that some might find the ellen sound slightly feminine.

An update on Manfred perhaps, with a cool literary tie to Jane Austen's novel, Mansfield Park, Mansfield is an English surname, borrowed from a variety of places in England. It may be interpreted in two ways: as a blend of manu and feld meaning "man" and "open country or field" respectively, or as a mix of Maun (a Celtic river name), again with the aforementioned feld.

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.

Alexander has been in a Top 25 boys' name in the US for 30 years now. But namers are still attracted to its imposing historic pedigree.

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.

Cornelius, the New Testament name of a third century Pope and saint, is one of those venerable Latin names on the edge of consideration, despite the corny nickname alert.

Frederick, and friendlier nickname Fred, seemed almost to have disappeared, leaving just the memory of Freds past such as Astaire, Mr. Rogers and Flintstone. But today's parents are beginning to recognize it as a strong classic and one of the top royal baby boy names.

Augustine is more substantial (and saintly) than August, less pretentious than Augustus, and, along with its nickname Gus, is definitely a viable choice.

Peregrine is considered to be an elegantly aristocratic name in England, but has never made it to the U.S., where it has been seen as extravagantly eccentric. In the new naming climate, though, it's not beyond consideration — in fact it's already been chosen by at least one Berry.

The short form Archie is so open and friendly --and very trendy in the British Isles--that some parents are now beginning to consider the formerly fusty Archibald as well. SNL comedians Amy Poehler and Will Arnett are one couple who made this breakthrough choice.

Valentine is an attractive Shakespearean name with romantic associations, but those very ties to the saint and the sentimental holiday have sent it into a decline, one which we think may be about to turn around.

The name Christian has fallen a bit from its 90's and 00's heights, but it's still quite popular. Once considered overly pious, Christian is now seen as making a bold statement of faith by some, while also having secular appeal for others. Christian's enduring popularity may be influenced by such celebrities as Christian Slater and Christian Bale, not to mention the fashion world's Dior, Lacroix, Louboutin and Audigier.

For every Tio Salvador in a Latino family, there's a Zio Salvatore in an Italian one. Having always ranked in the US Top 1000, it is in danger of falling off the charts very soon.

This name of three early popes has been associated in recent years with a cocky cartoon cat ("Thufferin' thuccatash!") and the Italian Stallion hero of the Rocky and Rambo movies (who was born Michael) — and yet we think it just might be ready to move further back into the mainstream.

The great American novelist sets this above many other surnames (and nature names, for that matter), but it's still an imposing and adventurous choice. Do nicknames Hawk or Thorne make it more approachable? How about Hank or Hal instead?

Classical and Shakespearean name that may appeal if you like your names long, flowing and multicultural.

This distinguished name still feels a bit ancient, but with the rise of such former graybeards as Jeremiah and Elijah, it also sounds child-friendly again, as does the Latin-Greek form Zacharias.

This evocative name of one of the Three Wise Men of the Orient, also spelled Balthasar, may finally be ready for prime time. Balthazar, Melchior and Caspar were the Magi who brought gifts of gold, frankincense and myrrh to the baby Jesus, though their names were not mentioned in the Bible.

Francisco is one of the more popular Spanish names for boys in the US, which is unsurprising given its popularity back in Spain and Portugal as well as Latin America, coupled with its classic status. It also has a cool hipster vibe to it, given the reputation of the city of San Francisco.

Endellion is the name of an early saint who was a daughter of King Brychan and goddaughter of King Arthur whose life is commemorated by the Cornish village of St. Endellion. This intriguing ancient name was brought into modern usage by British Prime Minister David Cameron, who used it as one of the middle names for his fourth child (a daughter).
