There is this ITV Special coming out about JKR sometime soon, and today The Sun newspaper published a close-up of JKR's drawing of Harry's family tree showing the names of his three children.

Uh-huh, yep. The oldest has "Sirius" for a middle name. Shall we vomit separately or at the same time? At least that explains why the little snotrag named for two Marauders was picking mercilessly on his younger brother.
