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.

Even less subtle than Duke or Earl, this name shot up the popularity charts in 2013, the same year young Prince George was born and the craze for all things royal (and Royal) began. Today, it's a leading boys' name on Nameberry's own popularity charts.

Mabel is cuddly Victorian favorite rising in popularity in the US, after a 50-year nap If you love offbeat old-fashioned names like Violet or Josephine, only sassier and bubblier, Mabel is one for you to consider. It is currently in the US Top 200 and the UK Top 50.

Jasper originated as a variation of the Latin Gaspar, which ultimately derived from the Persian word ganzabara, meaning "bringer of treasure." As a given name, Jasper’s etymology is unrelated to that of the gemstone, which comes from a Semitic word meaning "speckled stone." Jasper is the usual English form for one of the Three Wise Men who brought gifts to the infant Christ according to medieval tradition and appears in the Bible as a reference to the stone itself in Revelations 4:3.

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.

Cordelia is exactly the kind of old-fashioned, grown-up name for girls that many parents are seeking for their daughters today. The name of King Lear's one sympathetic daughter, Cordelia has both style and substance along with its Shakespearean pedigree.

Lennox is an aristocratic and powerful Scottish surname name made truly special by that final x. The worldwide fame of British boxer--World and Olympic champion--Lennox Claudius Lewis brought the name into the spotlight as a first name, while as a last it's tied to Eurythmics singer Annie L.

Lottie is a nostalgic great-grandma name that conjures up lockets and lace, and — like Nellie, Josie, Hattie, Tillie, and Milly — has considerable vintage charm.

This pet form of such names as Winifred and Edwina and Gwendolyn has loads of vintage charm, a la Millie and Maisie, with a decidedly winning vibe. And it just got celebrity cred as the baby daughter of Jimmy Fallon.

Walter was seen as a noble name in the Sir Walter Raleigh and Sir Walter Scott era, but it then spent decades in baby name limbo.

A strong, grounded choice that still has plenty of energy and charm, Leona is the feminine form of Leon, itself derived from the Greek word for "lion".

Angus is a traditional yet stylish choice in the UK, especially in Scotland. And it's a cool choice for US parents too, particularly those whose roots go back to Glasgow. The ancient Celtic form Oenghus has important historical overtones in Scotland, and the Gaelic form Aonghas is associated with two distinguished modern poets. In Irish folklore, Angus Og is a chieftain-lord who used his magical powers for the pleasure and prosperity of mankind--and in Irish myth, Aonghus was the god of love and youth.

Alec, though an old nickname for Alexander, is much fresher sounding than Alex, with the additional advantage, at least to some parents, of being distinctly male (there are as many girl Alexes these days as there are boys). While Alec has a clipped British image, it's actually one of the classic Greek names for boys, by way of father name Alexander.

Wilfred is one of those Old Man Names that still sounds fusty in the US but is fashionable in the UK.

Theodora is one of the most revival-worthy of the charmingly old-fashioned Victorian valentine names, softly evocative but still substantial, as is the reversed-syllable Dorothea.
