I'll probably have a hard time getting to sleep because of that unintentional nap, and I don't know when the aches caused by sleeping on the floor will go away. Annoying. But I can go see today's Daily Kitten to cheer me up.
Spatial-Literacy.org (apparently an academic neologism for geographical knowledge) is a site maintained by a group of English universities. They have just launched a section which tracks distribution of 25,000 surnames in Great Britain, using figures from the 1881 census and 1998 electoral register. The site is running slow right now, and the search function may be unavailable due to the amount of press they've been getting, so if you want to see where your Cholmendeley or Baggins or Bracegirdle cousins have migrated around the island in the last century, you may have to be patient. In the meantime, there is also a bit of interesting stuff to read about the classification of surnames. Of course, I want to see the maps! Show me the maps, dammit!
