Well before i thought that it might be dumbledore b/c he cares about muggle/wizard relationships and stands up for muggleborns and half-bloods. Im not sure if he is pure blood or not. Of Coarse his brother Aberforth was a wizard to so it is more likely that Dumbledore is a pureblood. Then again, Colin and Dennis are wizards that have a muggle milkman father (Colin says in the second book that he didnt know about the wizarding world until he got his letter so this means that either his mom is a witch and didnt tell them, is dead/gone and never had a chance to tell them, or isnt a witch at all and the fact that the brothers are both wizard is a rare coincidence). So It might be Dumbledore if he is a halfblood. A regular halfblood wouldnt be the prince, it would have to be someone who did something for the halfbloods. Like advocated their rights and fought against 'racism' from the pure bloods.

I hope this isnt confusing. I can see how it might be... sorry if it is I tried to make sense of what I was trying to say. lol. Interesting article though. We'll have to wait to see if any new info surfaces. Thanx for the Info Marcella Riddle!
