Effortlessly stylish, with plenty of sweetness and strength, Valentina feels like a fresh alternative to Valerie, Victoria, or Vanessa.

The name of a martyred medieval saint, Valerie has been on the popularity list since its earliest publication in 1880. Though it peaked in the 1960s, remaining in the Top 100 until 1988, it still doesn't sound terminally dated; the association with the word valor gives it a sense of boldness and makes it one of the special group of girl names that mean strong.

Vanessa was invented by writer Jonathan Swift for a lover named Esther Vanhomrigh—he combined the first syllable of her last name with the initial syllable of her first. Swift used it in the poem Cadenus and Vanessa in 1713. A century later, Johan Christian Fabricius used Vanessa as the name of a genus of butterfly.

Victoria is the Latin word for "victory" and a feminine form of Victor. It is the name of the ancient Roman goddess of victory, the equivalent of the Greek Nike, and also a popular third century saint.

The Viktor form of this classic name is widely used throughout Europe and is rising in the US as well.

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.

Ylva may look like it belongs with the Eva family of names, but it actually derives from Ulf, a name meaning "wolf." It's not a very intuitive name to English-speakers, and likely won't get picked up in the US anytime soon. At last count, it was only given to five American baby girls.

Zoe is one of those surprising names that has been on the Top 1000 nearly every year since 1880, but it's only since the turn of this century that it's ranked in the Top 100.
