From the saintly name Eligius, Eloi is popular in Catalonia but rarely used by English speakers. There's potential for confusion with Eli - and with the Aramaic word eloi, said to mean "my God", which appears in the bible.

Ethan is a name that succeeds in being at once classic and fashionable, serious and cheery, strong and sensitive. Given a big boost via the name of the Tom Cruise character in the Mission Impossible film series, Ethan has fallen from its peak at Number 2 in 2009 and 2010, but is still popular in the US along with several other countries.

Only if it's a family name, and even then, better in the middle.

Ferdinand, a traditional name in the royal families of Spain and a handsome young prince shipwrecked on Prosper's island in Shakespeare's The Tempest has, unfortunately, to the American ear a somewhat heavy and clumsy feel – most likely because of the bull connection. In the 1880's it was in the 200's on the US pop list, but has been off completely since 1986.

This is an ancient saints' name well used in Ireland but a rarity here and unlikely to ever reach the popularity of other Finn-ish names. St. Finbarr (the more common spelling) is the patron saint of Cork and in Irish folklore, Finbarr was king of the fairies.

One of the surname names used more in the last century, à la Milton and Morton.

Gabriel has become a biblical favorite, an angelic choice that's lighter and less patriarchal than some of his Old Testament brethren. Derived from the Hebrew name Gavri’el, Gabriel is taken from the elements gever, meaning "strong," and ’el, in reference to God.

Iconoclasts though we may be, we like Fred, we like Frank, and we like George, which was among the Top 10 from 1830 to 1950, when the number of little Georges started to decline. Solid, strong, royal and saintly, yet friendly and unpretentious, we think that George is in prime position for a comeback, especially since it was chosen by Britain's royal couple.

The chic Euro spelling of Henry is rising along with the original form.

Henry is back. The classic Henry climbed back onto the Top 10 in the US in 2021 for the first time in over a century, and now stands at Number 8.

Patrician to the core, Hugh was firmly in the Top 100 until 1903. It's never achieved those heights again, though it has always managed to remain in the Top 1000, scraping bottom at literally Number 1000 in 2006 before reversing course and heading back upwards.

Isabel and Isadora are back: could it now be time for a more widespread revival of Isidore? In 2014, both Isidore and Isadore were on the list of fastest-rising names in the US.

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.

Jason, the Number 3 name for the entire decade of the 1970s -- thus the title of our original baby-naming book, Beyond Jennifer & Jason -- is more likely to be dad's name now than baby's, but it's still a widely used name.

Jerome has a bespectacled, serious, studious image, just like its namesake saint, who was a brilliant scholar. St. Jerome is the patron saint of students, librarians, and archaeologists.

Jovan, the name of the supreme Roman deity, seems more extraterrestrial now -- and it's also firmly attached to a perfume label. Some parents may see it as a variation of Giovanni, the Italian for John. It is in fact the Slavic variation of John and may be an original way to honor an ancestral John.

Long popular in Ireland and England, Kieran, the name of Ireland's first-born saint and twenty-five other saints, has been building its U.S. fan base thanks to its strong and attractive sound, and its fashionable Irish brogue. While Ciaran is the more authentic Irish spelling, Kieran is more popular this side of the Atlantic.

This aristocratic, somewhat formal Germanic route to the popular Leo is a royal name: Queen Victoria used it to honor a favorite uncle, King Leopold of Belgium. Though Leopold sounds as if it might be a leonine name, it's not really a relative of such choices as Leon, and Leonard.

Levi, lighter and more energetic than most biblical names, with its up vowel ending, combines Old Testament gravitas with the casual flair associated with Levi Strauss jeans.

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.
