A non-AS related post, about Asperger as a name.
It is, of course, of German origin, and comes from the town of Asperg, very near Stuttgart. In turn, the town's name seems to have something to do with the aspen tree.
Obviously prevalent in the German speaking countries (Hans Asperger was Austrian of course), I also found on a Google search the actress Cynthia Asperger, who I think is Croatian.
In the USA, the surname appears to be concentrated in Ohio, Indiana and Illinois. When Googling, I found some law firms around the USA called Asperger too. They are so named because they have partners called Asperger, but I bet they are approached a lot by people with AS>
