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.

A versatile classic, Lucy is both sweet and solid, a saint's name, and the heroine of several great novels. First fashionable in England and Wales, Lucy is now a popular choice in the US, The Netherlands, and New Zealand.

Sadie started as a nickname for Sarah, but their images couldn't be more disparate. Where Sarah is serious and sweet, Sadie is full of sass and fun.

Cyrus is one of those surprising names that have always ranked among the Top 1000 boy names in the US. On an upward trend since the mid-90s, Cyrus now sits in that comfortable place between too popular and too unusual.

Wyatt has been hot, which is to say cool, for several years now. With its easy Wyatt Earpish cowboy charm, it's relaxed but still highly respectable.

Poppy, unlike most floral names which are sweet and feminine, has a lot of spunk. Long popular throughout the rest of the English-speaking world, Poppy is finally starting to rise toward the top in the US, where it entered the Top 1000 for the first time in 2016.

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.

Scarlett Johansson is doing more for this sparky southern name than Scarlett O'Hara ever did. Since the turn of the 21st century, Scarlett has gone from an obscure literary name to one of the most popular girls' names starting with S, right after longtime favorites Sophia and Sofia.

With its sharp, succinct sounds and cool, laidback style, Eli is a popular choice among parents today. Compact and punchy, it is a Biblical name with plenty of charm.

Grayson, which you might think of as a Jason-Mason substitute, has been rising through the US Top 1000 since 1984 and has ranked in the Top 100 since 2011.

Avery is a hugely popular name in the US, especially for girls. But while nearly four times as many girls as boys are named Avery today Avery's popularity is starting to soften for girls while it continues to strengthen for boys.

Zoey is a modern spelling variation of Zoe, the Greek Jewish translation of Eve. For a few years, it was even more popular than the original Zoe, but has now dropped back to the second-ranked spelling — not by much, however. In a recent year, Zoe ranked at #29 in the US, which Zoey featured at #59.

Knox is an old Scottish surname that Brad Pitt (whose great-great-grandfather was named Hal Knox Hillhouse) and Angelina Jolie took out of the back cupboard, dusted off, and elevated to coolness--to the point where it entered the popular baby names list in 2009. Knox now ranks among the most influential celebrity baby names.

Nash is an English surname whose sound puts it right in step with currently trendy names like Cash, Dash and Ash.

Colton is a trendy two-syllable choice, with the popular 'on/en' ending.

Hadley, most famous as the name of Ernest Hemingway's first wife, is more sophisticated, professional, and modern than cousins Harley, Haley, or Hayden. The hit book The Paris Wife, a novel by Paula McLain told from the point of view of Hadley Hemingway (born Elizabeth Hadley Richardson), has helped popularize the name, which also appears on the vampire show True Blood. Hadley could become this generation's Hailey. Adley, a mashup of Hadley and Addie, has also appeared on the scene.

A doubly Presidential name, via Pierce and Roosevelt, Franklin was given an initial boost via the fame of Benjamin Franklin. It also has a literary tie to the main character of the Wilkie Collins classic The Moonstone.

Sweet and cosy with a touch of sass, this nickname-y choice was a familiar option up until the sixties in the US. Then, for a while, it was a bit of a one-person name, associated with singer Dolly Parton, but more recently, it's been singing a fashionable note again along with sisters Dottie and Millie.
