Who isn't in the black Family Tree

Just some thoughts looking a the fuller version of the Black Family Tree...
..It is interesting that the tree seem to include mentions to most of the pure-blood families introduced in the books...from the Weasleys, to the Potters, Longbottoms, MacMillans, Crouches, and so on...This is not really a surprise, because, as we know from OotP, the pure-blood families are more or less all interrelated.
I find interesting that the tree is not featuring quite an important surname in the wizarding world..."Dumbledore". JKR herself said that asking questions about Dumbledore's family would be a "profitable line of inquiry"...If we consider that Dumbledore is about 150 years old at the time of the events in the books, the tree goes back to more or less the time of his birth...I wonder if he and Aberforth are the last of the family...if the family was half-blood, pure-blood or even Muggle? There are no suggestions about Aberforth's magical abilities, besides that he lives in Hogsmeade (an all-wizard village).
The Dumbledore family seems to hold some crucial bit of information, and I don't thin it has to do with the "Gryffindor Heir" theory, but with something else, perhaps related to choices/events around the matters of blood purity.
Any ideas?
