I came across this site today looking at some things out of curiosity.

One thing that surprised me is just how common the names Tracy and Marion are for guys in the US compared with Europe. These numbers seem to be supported by this site too. Whenever I see the name Tracy I always assume it is a girl, and the name Marion was so common in France for girls that I can't think anything different. I've yet to meet a male Tracy (although I have heard someone mention one to me) or a Marion, but I thought it interesting. Here in the US I happen to have a name that is relatively well used on girls, but if a male american Tracy or Marion went from the US to Europe, then they would be in the reverse situation to me.
I know some people say that the birth records and census data can be a bit shaky when you get down to the lower end (I also noted that a lot of the time the frequency is the same which implies that they just just happen to fall in that distribution sample, like a histogram bucket), but I am sure that they can't be totally off either. Plus from the names people do suggest here, I think we can see that there are all sorts LOL!
