Hmm what could it mean? Harry is a prince? Voldie is a prince? Someone else is a prince? Prince William/Harry/Charles is a half-blood wizard? Is the word 'prince' not actually referring to someone of a royal bloodline but of someone of noble intent?
Oh the possibilites.
The site is actually very good. There's something very satisfying about earning all these snippets of information rather than being told them.
