So apparently JKR's new website reveals that Ginny's full name is Ginevra.

So... yeah.

The WIAN nut in me is now destroying entire cityblocks in a frenzied rage.

Edit: Wait! No, there could be something here! Forget Arthurian theories or the line of English monarchs! "Ginevra" is the Italian name for Geneva, in Switzerland. Geneva, Geneva... Geneva Convention? Hmm, I shall ponder this some more.

(Or, you know, it could always be a reference to the character in Bite Me.)
