In "Harry Potter and The Half-Blood Prince" we learn that the mother of prof. Snape is/was a pureblood witch named Eileen Prince. Yet the Prince family is excluded from this list of all-magical families.

- Note that this list is not meant to include all pure-blood families. Pottermore specifies that it includes only those families the author felt were "truly pure-blood", that is, without a drop of Muggle blood in their direct line. Note that several other pure-blood familes, most glaringly the Potters, are also absent. -- 1337star (Drop me a line!) 00:35, March 23, 2013 (UTC)
As pointed out by the "behind the scenes" section, Garrick Ollivander was born a half-blood before the Directory was published. Is this possibly a mistake, or a JK Rowling slip-up? - both Mr Ollivander's blood purity and the Sacred Twenty-Eight were revealed on Pottermore. Should we abide by the canon hierarchy, and assume he is a Pure-Blood, as the Sacred Twenty-Eight is a newer source? 18.104.22.168 20:29, May 29, 2013 (UTC)
- I would prefer to err on the side of caution, personally, as I think one of the explanations provided in the Behind the scenes section could fit. Yes, the author of the Pure-Blood Directory' did list the Ollivander family as pure-blood, but it doesn't specifically contradict that Garrick was half-blood.
