Haha, thanks for all the comments. I know it has been a surname but as Tinkerbelles mum has said in these days most popular names have been/are to some extent.
As for Australian/American etc etc it doesn't bother me if it makes someone think of a fictional soap the other side of the world, I bet you could find anyone in some random programme with everyones name. I believe I'd be in Home & Away(well, maybe not now but about 4yrs ago), House & Dirty Sexy Money, although my name isn't Australian or American...
Chavvy to one area is not to another, here Jack, Charlie & Harry & Lewis are considered to be 'Chavvy' and Elijah, Ethan, Noah etc seem to be the 'replacement' therefore are becoming popular, so will these end up becoming chavvy in your terms? The Chavvy thing does honestly confuse me!!
