Is Lilly really muggle born? I'm convinced of the Lilly is related to 
the Heir of Slytherin through LV theory. What else can be done with 
all the green eye references?  Green being so strongly associated 
with Slytherin. Weak I know but read on:
  
OK, we do have overwhelming evidence that Lily was muggle born as 
both LV (as Tom Riddle) in CoS and Snape in OotP called her a 
mudblood. We also know that Lilly has to the sister (or blood related 
to Petunia) in order for her special protection to work while Harry 
is in their house in Privet Dr.  So where can the connection be?  

I propose Lilly is only the half sister to Petunia.  They share the 
same mother but have different fathers.  Lilly's mum met and married 
Mr. Evans when she was pregnant (or Lilly was a just a baby).  Mr. 
Evans adopted Lilly as his own.  This preserves the blood connection 
to Petunia, and lets everyone believe Lily is muggle born and allows 
her to be the daughter of LV.  

I've believe Harry to have been the true Heir of Slytherin since 
CoS.  There is nothing to say the Chamber didn't open in Harry's 
first year at Hogwarts but as he knew nothing about it lay dormant 
and quite until someone (LV as Tom Riddle through Ginny) got in there 
to awake the Basilisk. It is also possible for Harry can be the Heir 
of Slytherin and "a true Gryffinor" as we know one can be born to 
a 'bad' family and yet be good, as with Sirius'.  Or, born into a 
good family and be rotten egg, as with Percy. 

One last thought.  The sorting hat's new song sang about uniting the 
houses of Hogwarts or the school would fall. Hermione can see this 
coming and has suggested they do something about it in OofP but Harry 
and Ron laughed at her stating that Gryffindors and Slytherins would 
never get along.  If that is true Hogwarts is doomed. Uniting the 
Heir of Slytherin and Gryffindor in Harry may be Hogwarts only way 
out.
