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.

Oscar is one of the most stylish Old Man Names of our era. While it's softened slightly in popularity over the past 20 years, that may be considered a very good thing.

Rufus is a rumpled, redheaded (it was the nickname for red-haired King William) ancient Roman name popular with saints and singers (e.g. Rufus Wainwright); now, Rufus is on the cutting edge of cool.

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.

Earthy but sophisticated, Marshall is an occupational surname, and despite the sounds, it isn't military or martial in any way. Rather, it stems from the Norman French for someone caring for horses.

The French-accented Pascal was historically used for sons born at Easter, and can make an interesting choice for a boy with Gallic roots arriving around that holiday.

Kiefer is a strong occupational surname associated with "24" star Kiefer Sutherland, but one that could well join the other 'er' surnames currently in favor. Keifer is a German surname transferred to first name use, derived from two old Germanic words, kien and forhe, both of which mean "pine tree."

The "Believe It or Not" jokes will get old fast, but this surname feels fun and on-trend for both girls and boys, reminiscent of Riley, Tripp, Bridger, and Oakley.

Tennis star Novak Djokovic introduced this new first name to the English-speaking world, though it had long been familiar as a surname. The celebrity Novak, one of the greatest tennis players of all time, might be an inspirational role model for a baby Novak. And the name Novak goes well with other stylish names that mean new, including Nova, Neo, and Nouvel.

Bland compared to the Irish-sounding O-starting names, but fans of football star Odell Beckham Jr. may like the name for other reasons.
