The BBC website had a story this morning about the Global Surnames Profiler. Type in your surname, and you'll get a map of the world showing in which countries your surname occurs most often (frequency per million).
The site is here.
I tried it first thing for "Seel" and "Youell". We're big in Germany, where "Seele" means "soul". At the moment the site is completely busied out as more people wake up and try to use it.
Try it tomorrow.
