Amanda's just prompted me to ask something that's been bugging me for ages
about how purity of blood is judged.  Obviously, there are the three
categories that we've heard of: muggle born (not mudblood, please! ;-) ),
half-blood and pure-blood, which I understand, but would there be degrees of
half-bloodedness?

If your parents are, at the most basic level, a witch and a wizard,
regardless of birth, does that make you a pure-blood?  Harry's parents are a
muggle-born witch, and, AFAWK, a pure-blood wizard, whereas Seamus is
definitely half and half because he says so, despite being a wizard, as his
father is a muggle; does this make Harry a pure blood, being descended from
a witch and wizard, or something like, say, a 3 quarter blood?  Not that
purity of blood matters in itself, but if Harry was not considered to have
sufficient wizarding ancestors to make himself a pure-blood, surely that
would put Voldemort on shaky ground with his own policies of purity of the
gene pool?
