Where in the world is Carmen San Diego? If you search for her using the World Names Profiler map, apparently "Sandiego" is mostly found in France. I saved this little gem for the weekend because you'll want lots of time to play with it. Just plug in your last name and see where most of your kinfolk live, instantly.
This map is for "Smith," which isn't as worldwide as the Witness Protection Program might like you to think. . . I've heard, anyway. Now go search for your own name, it's fun and easy! Where is your family tree planted?
