Naaaa! I've just had another look at the prophecy and it's pretty clear that the same one that is "marked" is the same one witht he power to "vanquish" is the same one who "can't live while the other lives"... therefore the prophecy can't be shared by Nev and Har. Still, worth a try.

I also, on further thought, find it difficult to believe that Voldemort would have sent the uninformed Lestranges to the Longbottoms. If Voldemort had any REAL belief that Neville was the 'One', he'd have gone himself.

What have the Longbottoms got to do with this? Theye weren't secret keepers for the Potters, what did Voldy need to find out from them? Why aren't the Longbottoms dead?
