Your mission, should you decide to accept it (cue the Mission Impossible music...), is:
1) Find out the geographical distribution of your surname - in the world, in your state or province, in your county or parish. I suggest that you use the Public Profiler site at http://www.publicprofiler.org/worldnames/, which seems to work quickly and easily. However, you cannot capture the image as a photo file - you have to capture the screen shot, save it and edit it.
2) Tell us about your surname distribution in a blog post of your own (with a screen shot if possible), in comments to this post, or in comments on a social networking site like Facebook and Twitter.
Here's mine (without editing the images):
I went to the Public Profiler site and entered "Seaver" in the Surname field, and saw a world map:
There is a handy list on the right with the top five countries, in persons per million with the surname.
You can "mouse over" the countries and click on a country - I chose the USA:
Then you can click on a state or province on the USA map - I chose California:
The colors on the map correspond to a range of "low" to "high" surname frequencies based on frequency per million (FPM) people. However, the "high" range for one surname does not necessarily mean it has the same FPM as another surname with a "high" FPM.
