Ginger:  It is easy to miss it at first read (I did myself), but 
Tonks is a full-blood.  It is her father that is Muggleborn.

Ginger:  Tina has covered this well.  I am convinced by her words 
that these two belong in the full-blood category.

Ginger:  Molly and Arthur seem to be pureblood.  I don't have any 
hard evidence for Molly, other than her being a Prewett, but Arthur's 
facination with plugs etc. and general ignorance of all things Muggle 
would lead me to believe that he is a pureblood.

Lupin is halfblood, per JKR interview (World Book Day chat).
Lavender has been seen as a Muggleborn by some listees as she didn't 
know what the Grim was.  I say that sounds reasonable.

I agree that it is interesting, but there are just too many 
unknowns.  Perhaps JKR will give us a bio sheet!  Oh the threads it 
could spawn!

Ginger, who admits that half of what she wrote here is knowledge 
derived from pressing her nose to the screen on this list, and that 
this post was done for the sake of accuracy, not to take anything 
from those whose original thoughts they were.
