"...here in Britain you would usually only hear those sort of names in (trying not to sound too snobby) kind of 'trashy', lower class families, and only VERY rarely."
Oh, dont' get America wrong my friend. 'Trashy' lower class families are really the only families who use creative names here in the US as well. I don't know any truly sophisticated families that have anyone with a creative name. So, in reality, the Brits and Yanks aren't that different.
