Dumbledore's family

For a little diversion from the current long threads,
has anyone given much thought to JKR's comment that 
Dumbledore's family would be a good avenue to explore?
I figure she meant one of two things:

1. She was referring to Aberforth, of whose existence
we are already aware from the first OotP photo, and
who is very likely the current Hogs Head bartender.

2. She was referring to someone else. 

It could be that she is merely referring to Aberforth,
which does seem a bit odd to me, since we are already
aware of his existence. But he hasn't had much part in
the story, so maybe she is hinting that he will have
a much more critical role in DH. He is certainly the
most likely candidate for the "Order member we haven't
yet properly met." 

Or could it be someone else, someone in the story (as
JKR said she wouldn't be introducing any major new
characters in DH) whose relationship to Dumbledore
hasn't yet been revealed? Potential relatives might
include the Weasleys (who have red hair like Dumbledore),
the Princes (the wizard side of Snape's heritage--and
such a relationship might help explain Dumbledore's
determination to protect Snape's secrets as well as
providing a foundation for a deep knowledge of Snape,
deep enough to trust him and his motives completely),
or Godric Gryffindor (which might also tie Dumbledore
to Godric's Hollow). 

The ones who seem ruled out are the Potters and the
Evanses (Harry has no close living relatives besides
Petunia and Dudley), the Blacks (no Dumbledores on
their tapestry) and by extension the Malfoys. Other
families like the McGonagalls, Abbotts, Lovegoods,
Smiths, etc, aren't ruled out, but I don't see how
a family relationship between Dumbledore and minor
characters would be significant to the plot, or of
any real interest. 

Other thoughts?
