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)
