Fairly popular a hundred years ago but out of the US charts since 1978, the quirky yet edgy Roscoe feels very much in step with the trending o-ending boy names popular now, such as Milo, Hugo, and Otto. A Top 1000 choice in the UK (albeit near the latter end), it could make a cool alternative to Ross, Russell, Robert, and Ronan.

Sleek and smart, with a hint of mystique about it, Silas is a recent addition to the US Top 100. Both mythological and Biblical in origin, Silas joins the ranks of Isaiah, Atlas, Elias, and Sebastian: polished and contemporary feeling names with plenty of history.

Sleek, sharp, and soulful, Isolde is the German form of Iseult, the fabled lover of Tristan in the Arthurian romances. First appearing in the 12th-century, the name was fairly popular in the form of Iseult, Yseut, Yseult, and Ysolt, however, it wasn't until the 19th-century that this form began to catch on, after the composer Richard Wagner used it for his 1865 opera (and for his own daughter!)

Rugged but gentle at the same time, Cassian is a saintly and stylish choice that was derived from the name Cassius. Before 2017, it was an obscure choice, given to a tiny handful of boys each year. As of 2023, however, it's become one of the top ten fastest-rising names in the US, more than doubling in usage since 2022 and edging closer towards the Top 500.

This gentle Scandinavian name, soft and sensitive, is being discovered in a major way by parents in the US. It's most closely identified with the nineteenth century philosopher Soren Kierkegaard, but there have been modern fictional Sorens as well, in The Matrix Reloaded and the book series Guardians of Ga'Hoole, Charlie and Lola, and Underworld.

Magnus is a Latin name, literally meaning "greatest," that has a Scandinavian feel. It dates back to Charlemagne being called Carolus Magnus, or Charles the Great. Norwegian king Magnus I, named after Charlemagne, introduced it to his culture, and thus Magnus was the name of six early kings of Norway and four of Sweden. It is still a highly popular name in Denmark and Norway.

Romantic and mysterious, Eluned's beauty and intelligence were legendary in Welsh legend; she was the handmaiden of the Lady of the Fountain in a Welsh Arthurian romance, who had a magic ring that made the wearer invisible. Pronunciation is usually similar in emphasis to Eleanor, but with ned instead of nor at the end. However, it's sometimes also pronounced el-LIN-ed or even shortened to Luned, the sounce of Lynette, in Tennyson's Gareth and Lynette.

This hauntingly euphonious Choctaw name has re-entered the public domain, as memories of the outrageous actress Tallulah Bankhead have faded. For years, Tallulah was a name associated only with Bankhead, named for her paternal grandmother who was named after the Georgia town of Tallulah Falls.

Bodhi is a Sanskrit name translated as "enlightenment" or "awakening" which relates to a Buddhist concept, wherein Bodhi is synonymous with the state of nirvana, being freed from hate, greed and ego. The Bodhi tree is a large fig tree under which the founder of Buddhism received enlightenment. Spelling variations include Bodie and Bode.

Tristan -- known through medieval legend and Wagnerian opera -- has a slightly wistful, touching air. This, combined with the name's popular "an" ending, makes Tristan very appealing to parents seeking a more original alternative to Christian.

Caius is classical and serious but also has a simple, joyful quality. There was a third century pope named Caius, as well as an early Christian writer, several Shakespearean characters, and a Twilight vampire. We would pronounce the name to rhyme with eye-us though at Cambridge University in England, where it's the name of a college, it's pronounced keys.

Stellan is a strong, attractive, Scandinavian possible up-and-comer, known through actor Stellan Skarsgard, and his namesake, the son of Jennifer Connelly and Paul Bettany. Its trendy 'an' ending and the similarity in sound to the popular Kellen/Kellan make it all the more accessible.

Lysander is a distinctive Greek name that could be thought of as a more creative cousin of Alexander. In ancient history, Lysander was the name of an esteemed Spartan naval commander and his literary cred comes from one of the two star-struck young men in Shakespeare's A Midsummer Night's Dream, as well as one of the twin sons (the other being Lorcan) of Luna Lovegood, whom we learn about in the Harry Potter epilogue.

A strong single-syllable surname with a joyful meaning, Tate is finding a place on more and more birth certificates.

Jace may sound like only half a name -- it's usually pronounced like the first half of Jason though some may consider it a spelling-out of the initials J. C. -- but it's a popular choice for baby boys. Jace has been heard on such TV shows as Teen Mom 2 and Duck Dynasty.

Since Aurelius was given the supermodel seal of approval by Elle Macpherson, it has joined Augustus as an ancient Roman name that feels usable today. Slightly mystical and magical with a golden hue, Aurelius is grounded by its similarity to rising stars Aurora, Aurelia, and Atticus.

A top ranking choice in England and Wales, making frequent appearances on the Telegraph Announcments, Rafe feels equal parts rugged, amiable, and posh. Traditionally seen used a variant of Ralph (itself from the Old Norse Ráðúlfr), it came into use in the 17th century to reflect this particular pronunciation.

Tamsin is an offbeat name occasionally heard in Britain and just waiting to be discovered here. U.K. actress Tamsin Greig is a star of the show Episodes, Tamsin Olivier is the daughter of Joan Plowright and Sir Laurence Olivier..

Casimir, a traditional name of Polish kings, could do quite well these days as we see the rise of Caspian, Cassius, Castiel, et. al. Like Leopold and Laszlo, Casimir is strong and worth considering if you've got an adventurous streak — and bet your son will too.

A name of multiple identities: a somewhat soap-operatic single-syllable surname, a homonym for the biblical bad boy Cain, and, when found in Japan and Hawaii, it transforms into the two syllable KA-neh. Kane also has multiple meanings: in Welsh, it's "beautiful"; in Japanese, "golden"; and in Hawaiian, "man of the Eastern sky."
