Accents

[susanbones2003]

Can someone (I shouldn't ask for anyone personally, say Nicholas for 
instance....) please map out the accents for me. Where in your humble 
opinion are these kids'accents from? I thought Tom's accent was not 
posh enough for someone who's supposed to be pureblood. I know this 
must have come up so if someone wants to point me to a good 
explanitory post, I will humbly accept that.
