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.

Seraphina is one of the most-searched name on Nameberry, destined for even greater popularity. The highest-ranking angels, the six-winged seraphim, inspired the lovely name Seraphina.

Astrid has been a Scandinavian royal name since the tenth century, and many people associated it with the Swedish author of the Pippi Longstocking stories, Astrid Lindgren. Astrid is derived from the name Ástríðr, which is made up of the Old Norse elements that mean "god" and "beautiful."

Percy is an adorable old name that is finally shedding its pampered Little Lord Fauntleroy image in this new era of boys with soft yet traditionally male names like Jasper and Elijah. Originating as an aristocratic Norman name, Percy became fairly widespread in England--and to some extent in the US--as an offshoot of the fame of the poet Percy Bysshe Shelley.

Rupert is a charming-yet-manly name long more popular in Britain (where it's attached to a beloved cartoon bear) than in the U.S. Yet we can see Rupert as a more stylish, modern way to honor an ancestral Robert.

Linnea is an attractive Scandinavian name that derives from the renowned 18th century Swedish botanist Carl Linnaeus, who developed the Linnean system of classifying plants and animals.

Siobhan is the Irish variation of Joan, which is derived from the ancient Anglo-Norman name Jehanne. In this way Siobhan is indirectly related to the name Sinead—the Irish form of Jeannette, which also derived from Jehanne—although Sinead is not a nickname for Siobhan. Siobhan was the name of several early Irish queens and was introduced to the American public by the actress Siobhan McKenna.

Now seen as the chap in the smoking jacket in a 1930s drawing-room comedy, Reginald has actually been on the US popularity list every year since 1880.

Despite her somewhat prissy, puritanical air, Priscilla has managed to stay widely used for well over a century -- it reached as high as Number 127 in 1940 -- appreciated for its delicacy and solid history.

The biblical Judith, the fourth most popular name in 1940, may be getting ready for a comeback in its full, elegant, if somewhat solemn form. Many of those earlier Judiths were called Judy—some after Judy (born Frances) Garland—preferring it over their more formal proper name. Today, Judith, like Deborah, may have shaken off just enough to appeal to parents looking for a traditional, yet under-the-radar biblical name. And Jude would be a likelier nickname these days than the Judge Judy connection.

Artemis, one of the key figures of the female Greek pantheon, is the ancient virgin goddess of the hunt, wilderness, animals, childbirth, and a protector of young girls, later associated with the moon. Artemis is the equivalent to the Roman Diana, but a fresher and more distinctive, if offbeat, choice.

Thatcher is an open and friendly freckle-faced surname, fresher sounding than Tyler or Taylor, that dates back to the days of thatched-roof cottages. It is catching on with modern parents—it reached the US Top 1000 for the first time in 2013.

Like Ashley before it, on-trend Everly has been followed by a range of spelling variants, and among them, Everleigh is the most popular.

A name that feels both spiritual and trendy, Trinity surged up the charts in the early 2000s, following the release of The Matrix. In just two years, it made an impressive jump from the latter end of the charts to the US Top 100, where it remained for more than a decade.

Belinda, cousin of Linda and Melinda, enjoyed a brief return to the Top 1000 from 2005 through 2013, only to fall off again in 2014. A name that some may consider a modern spin on the midcentury popularity queen Linda is in fact a classic with deep and fascinating roots. In Babylonian mythology Belinda was the goddess of heaven and earth, and the name later was used for the heroine of Alexander Pope's satirical poem The Rape of the Lock.

Out playing shuffleboard at his condo and not expected back for several generations -- unless it morphs into a girls' name, a la Sydney.

Alaia, a fast riser in the US, sounds just like several other popular stylish names, many of them with different origins and meanings. There's Arabic Aaliyah, like the late singer, and the Hebrew Aliya and the Sanskrit Alaya. Azzedine Alaia is a high-fashion Parisian designer of Tunisian origin.

Troy shot to popularity as a first name in tandem with that of 1960s heartthrob Troy (born Merle) Donahue; its image has now, thanks in part to the Brad Pitt-starring epic, Troy, receded back to conjuring up the ancient site of the Trojan wars.

This strong single-syllable boys’ name has been finding favor with parents since the fifties, though it's been slipping in recent years; it fell out of the Top 500 for the first time since 1959 in 2015. Its main associations have been with the River Trent, whose name dates back to prehistoric times, and with former Mississippi Senator Trent (born Chester) Lott, and Trent Reznor (born Michael) of Nine Inch Nails.

Spirited and bubbly, but handsome and preppy too, Darby is a surname style choice that fits in well with the likes of Alby and Lennox.
