Dumbledore's Family, Who are they, what is their significance Options

[timeturner]

Here is another interesting quote from the Mugglenet/TLC interview of JK. I haven't seen or heard much talk about this (Dumbledore's family). Theories anyone?

ES: Dumbledore is unrivaled in his knowledge of magic –

JKR: Mmhm.

ES: Where did he learn it all?

JKR: I see him primarily as someone who would be self-taught. However, he in his time had access to superb teachers at Hogwarts, so he was educated in the same way that everyone else is educated. Dumbledore's family would be a profitable line of inquiry, more profitable than sweet wrappers.

MA: His family?

JKR: Family, yes.

MA: Should we talk about that a little more?

JKR: No. But you can! [Laughter.]

Personally, I think that Aberforth is just Dumbledore in Timeturner mode. After all, you ever seen the two of them together?

I actually like that theory. Does this mean I'm insane too?

I found a quote about age. I remembered reading it before. What is the deal with the part in ( )

Question: How old is old in the wizarding world, and how old are Professors Dumbledore and McGonagall?
J.K. Rowling responds: Dumbledore is a hundred and fifty, and Professor McGonagall is a sprightly seventy. Wizards have a much longer life expectancy than Muggles. (Harry hasn't found out about that yet.)

Same interview-

Question: Harry Potter for grownups again! Is Voldemort the last remaining ancestor of Slytherin, or the last remaining descendent of Slytherin?
J.K. Rowling responds: Ah, you spotted the deliberate error. Yes, it should read "descendent." That's been changed in subsequent editions. (Keep hold of the "ancestor" one, maybe it'll be valuable one day!)

And what does that mean?
