Aunt Petunia & Hogwarts (new theory, long)

 I agree that Lily is from a muggle family. Not only is it stated as 
a fact numerous time by numerous people (Hagrid, Dumbledore, Snape 
among others), having Harry be descended on both sides from wizarding 
families (even with squibs in the ancestry) would hugely dilute the 
themes of Harry's mixed ancestry (paralleled to that of Voldemort 
himself) and intolerance in the wizarding world.

On the other hand, I agree that Petunia knows far more about the 
wizarding world than living as a muggle with a witch sister (long 
rejected) would explain. The emotional intensity of her reaction to 
Dementors, as well as knowledge she quickly displays all indicate far 
greater and more intimate familiarity.

We have been told several times of muggles unknowingly marrying 
witches (Seamus and Voldemort are offspring of such unions -- note 
that the bit about Seamus is kept and emphasized in the movie).

What if Petunia was married before Vernon -- to a wizard?  This would 
be a dreadful secret she is trying to keep. Threatening her with 
exposure of it would be a convincing way to force her to let Harry 
live with her.  (Remember my last!)

Presumably for plot purposes this former wizard husband is someone 
important to the plot. Did not JKR say that marital status of at 
least one member of Hogwarts faculty would be integral to the plot?
Petunia is not unattractive (physically!), in fact we are told she 
looks a lot like Lily (except for her eyes) and presumably the 
resemblance would have been much stronger when she was young. Maybe 
Petunia is Snape's ex wife -- or Lupin's...
