<<<Marcie:
Lily must also have some Wizarding 
family somewhere in her ancestry, and I am assuming that Petunia has 
some magical abilities, too, but is more or less a Squib. It is 
understandable, too, that Petunia would estrange herself from her 
parents (if they were alive by the time Harry and Dudley were born) 
because she felt that they always favoured Lily, anyway. >>>
 

Now me (Sarah):
I am always at a loss whenever anyone speculates that Lily had a 
magical anscestor, to the point that Petunia would be a Squib.  
Genetically, if the wizarding gene is recessive, then Lily only 
needed her parents to both have one copy of the wizard gene.  That 
doesn't necessarily mean that Lily had two magical ancsestors 
somewhere in her background (one for each parent), just that this 
gene has been passed on through the ages.  I always took it that 
Lily came from a completely non-magical family.  (If any magical 
ancestors, so long ago that no one remembers them.)  Personally, I 
think that Lily and Petunia's parents are dead.  Petunuia definitely 
seemed jealous of Lily, but she also seemed to dislike her too much 
for the dislike to be mere sibling jealousy.  My pet theory, and of 
course I have no proof of this, is that their parents were murdered 
because of Lily.  (Maybe during one of her and James' escapes from 
Voldemort?)

I would similarly think that the Potters were also murdered.  If 
they were still alive, someone in the magical community would have 
mentioned it to Harry by now.  To not tell him that his grandparents 
were alive would be unnecessarily cruel.    I assume that they were 
murdered by Death Eaters for sport because of their association with 
a muggle-born witch.  The fact that they raised a son who alway 
hated the dark arts also leads to the thought that they also hated 
the dark arts.  An added insentive to dispose of them.
