From the time we wrote our very first name book, we’ve both been totally charmed by the unique verve and spirit of  names ending in the letter ‘o’.  And, over time, our love for them has only increased.  We’re glad to see that more and more people seem to be agreeing with us; lately there’s been an infusion of newly popular choices–and, surprisingly, this is beginning to be true for girls as well as boys.

Here are some of the currently coolest boys’  names, many of then reflecting the ever-growing globalization of baby names:
