Begins or Ends with O

This is a classic Italian name for boys, but despite the success of Luca and Matteo, has yet to catch on in the US. Vincenzo has made the charts in the US in only a couple years throughout the 20th century, but has been consistently on the charts since 2000. As Enzo becomes one of the hottest boys names in recent years, the elaborated Vincenzo may follow suit.

Old World Italian name that might become fashionable in a so-far-out-it's-in way, like Enzo and Rocco. Main recommendation: It's among the rare boy names that mean life.

Unusual Italian name for boys that relates both to the vividly stylish Viv names such as Vivienne and Viveca, and to the Italian musician Vivaldi.

Its jaunty o-ending makes this name more appealing than most of its Germanic brothers, and we hope we're beyond the constant response to his name being "Where's Waldo?" The weighty reputation of writer and philosopher Ralph Waldo Emerson adds a measure of backbone to the name.

Winslow, despite its creative connection to the distinguished American painter Winslow Homer, does still retain remnants of the image of a Victorian boy in a sailor suit, making Winston or even just Win a preferable modern choice.

Aside from President Wilson (born Thomas), most Woodrows, including Herman, Guthrie, and Harrelson, have chosen to be known as Woody, which says it all.

Zacheo is an Italian last name that is occasionally seen as a first name. Also used in Brazil (where it can be pronounced Za-shey-o), it could prove a little-known (to English speakers) alternative to Zachary.

Portuguese form of Zephyrinus, deriving from the name of the Greek god of the west wind, Zephyr. Saint Zephyrinus was a 3rd-century pope.

Unusual and attractive name, might be worth considering if you're expecting twins.
