How unique is your name?

In a desperate search for new material, I came across this on the internet.

HowManyOfMe.com

There are 0 people with my name in the U.S.A. How many have your name?

I knew the answer already, as my last name is very rare. I think there may not be another one person with my name in the whole world, never mind the U.S. There are however, 338,208 people with the first name Julia in the U.S.
Interesting -- there are 20 people with my husband's name.
