I'm sorry if this has been covered, but I couldn't find any posts so 
here goes:

I was just re-reading HBP (Chapter 20: Lord Voldemort's Request) where 
we meet Hepzibah Smith, and I was wondering if Zacharias Smith (the 
Hufflepuff prat) was/is related to her.  There seems to be a lot of 
emphasis on his haughtiness, and it's made clear that Hepzibah is 
quite fond of herself as well as quite rich.  I was wondering if there 
might be more to Zacharias than just being a jerk, and if that might 
be important later on.

Or maybe Smith is a very common name.
