(February 3, 2000)...
Q.  Do you take real people you know and put them in your books? 
A. <snip> John Weasley is a little bit like my oldest friend, a man 
I was at school with, whose name is Sean. But neither of them are 
accurate portraits. 

Who is John Weasley?  Could JKR have possibly changed the name of a 
character at this point (after PoA)?  Could John be the missing 
Weasley and JKR just slipped in giving his name?  Any other 
thoughts?
 
 
 Then Erin responded:  
I think Scholastic must have gotten it wrong, I've only seen that 
quote as Ron Weasley. Here is the best place to look at the 
interviews, if you're interested:

Now Hermowninny again:
Thanks for the link, it looks like a great site.  I will be spending 
a lot of time there.

However, I checked the interview in question and it still says "John 
Weasley."  Therefore, my original questions stand.

Anyone have any ideas?
