Danish Royal Family

Sophia, which was the Number 1 girls' name in the US from 2011 to 2013, is among the top girl names in the Western World, with a sensuous sound and high-minded meaning. A real winner, Sophia reached the top of the charts without losing any—okay, much—of its sophisticated beauty.

Ten years ago we would have advised people to steer clear of this name (and maybe choose the similar sounding Walter instead); but with the rise of other Nordic and Eastern European names like Viggo and Casimir, maybe its time to re-thing Valdemar. It's a big name, but with enough penache, it could be pulled off. Valdemar was introduced to Scandinavia in the 12th Century by a Danish king named for his Ukrainian grandfather, and is currently in the Danish Top 20.

Vincent is a name with a complex image. After being quietly used for centuries, it is suddenly seeming stylish, along wih other V names. Even the nickname Vince has been given a reprieve via actor Vince Vaughn and country singer Vince Gill. Vin Diesel was born with the more prosaic name Mark Vincent.

The American child given this name of four kings of Denmark, not to mention one so similar to that of the Harry Potter archvillain Lord Voldemort, might have to pay a large emotional import tax.

William is one of the most enduring of classic names for boys. It's also among the most popular boys' names, as American parents see it as being ideally conservative yet contemporary, and hands-down the most popular baby name beginning with W of all time.
