In the 'OK, this rumor is going to die right here' thread is a link to
an interview about death, but one other very critical piece of
information is revealed.

Quoted in part-
. . . . . . . . . . . . . . . 
Rowling is speaking-

"...He finds out that he (Harry) is a half-blood: to a wizard like
Lucius Malfoy, he will never be a true wizard, because his mother was
of Muggle parentage. ..."

. . . . . . . . . . . . . . . 

That pretty much solves that mystery.
