If one parent is a witch/wizard and one is a muggle - which world do 
they live in? The fact that Lily is referred to as a mudblood, and 
also Petunia's general behaviour would suggest that they were brought 
up in the Muggle world. However, Petunia's apparent knowledge of 
certain wizarding facts suggests she has had some contact with 
wizards i.e. her mum/dad. 
 
This leads on to a number of other questions;
 
(1) Does Petunia's knowledge of Azkaban stem from the fact that one 
of her parents was imprisoned there! (Hence there need to live with 
the Muggle parent)

Meltowne:
I suspect someone from the family was, but maybe a grandparent.  Or 
maybe someone who brought harm to the family.  We know Harry is 
considered a half-blood because of Lily's grandparents - but this 
does not mean ALL of her grandparents, but maybe only 1 was a muggle, 
though I suspect both on one side were, and perhaps one on the other 
side.  Maybe a good question would be, if a wizard and a muggle 
produce a non-magic child is that child a squib or a muggle?  If a 
muggle, then a child of 2 such people - maybe Lily? - with 2 wizard 
grandparents would still be considered muggle-born!
esmith:
(2) Is Godric's hollow the family home for Lily's mum or dad (and 
hence HP is descended from Gryffindor).

Meltowne:
I do think HP is descended from Gryffindor, through Lily, but don't 
think the family had lived there in a long time.

esmith:
(3) Is this theory absolute twaddle???

Meltowne:
All theories are fair game, until they are disproven either by canon, 
or by the next book.
