Baby Number Three - Top 20

Sid originated as a nickname for Sidney, but we like it on its own, a la Sara Quin's and Jason Biggs and Jenny Mollen's sons. Sid Vicious, member of the band the Sex Pistols, gives this name a punk rock vibe.

Wolf is a name with a split personality. It can be seen as one of the fierce animal names, like Fox and Bear and Puma, with a touch of the werewolf, or it can be viewed as a quieter, Wolf Blitzer kind of name, fairly common in German (where is pronounced Vulf) and Jewish families, sometimes as a short form of Wolfgang, or even Wolfram or Wolfhart.

The ultimate nicknamey name, à la Ziggy Stardust or the comic-strip character Ziggy. Then again, there's Ziggy Marley, and most anything Marley is cool. Originally named David, his father Bob Marley gave him the nickname "Ziggy" due to the soccer move of the same name.
