This new website showing you the geographical distribution of adults with a certain surname in 1998 and 1881 (and how many there were) is interesting (it's overloaded, so keep pressing refresh or clicking search and it'll work).Turner is unfortunately a common surname and we're all over the place (over 300,000 in 1998. So I will show you my mother's maiden name, Upchurch, of which there were only 425 in 1998.

ps This post will look terrible if you are using Firefox. Apologies, will try to sort it out sometime soon.
