What a neat thread. And while I haven't read all the posts, I will say that as a teacher, I am uniquely privy to the interesting trends in baby naming. I've had semesters where I had a handful of Kirstens, and recently it's been many Olivias and Emmas. (my school has a pretty big disparity between men and women). it's really bad when all the Kirstens pretty much look alike,.
When I taught in Detroit which was far more diverse than Massachusetts, I would always have at least 4 or 5 Mohammeds in class, all of which wanted to be called "Mo." Yeah, THAT got confusing.
What always broke my heart were the Chinese students who would come into my class and said just to call them "Mary." When I enquired as to their actual Chinese name, they would get this huge smile on their face because others were fine just calling them by their Americanised name.
