That would be "Sandy Klim"
The whole bank story sounded new to me too, so I thought that'd be cool to post here.....
I'm not THAT much into Harry Potter to know that Gringotts isnt in Hogsmeade....
Anyway, thats what the article says, I might scan it later today and post it here, its just 2 pages so that'll work...
Btw,
can it be possible that they (universal/WB/J.K. Rowling/ etc.) found a way to have Gringott's in WWOHP anyway?!

You just beat me to it, but that's just basically what I meant... in not so many words
