Silly Web Stuff: How many Americans have your name?
My wife would have a much more difficult time playing this game which I've dubbed "Name Highlander" ("There can be only one!"), as she would have to defeat 2,369 other people to lay sole claim to her first and last name. Interestingly enough, my son Quinlan apparently has no fellow first namers in the country, but 8,309 people have Quinlan as a last name. The shorter form of his name, Quinn, is much more common.
Another fun name applet is the Baby Name Voyager, which allows you to see how a name's popularity has risen and fallen over the years. It can tell you, for example, that people generally stopped naming their kids "Rupert" and "Enid" in the 1950's.
