Who knew that Peter was the Secret Keeper? (Was: After all this time...)

Thanks, Talisman, I went and looked.

In case anyone is confused, JKR has posted the answer to the question 
of "What happens to a secret if the Secret Keeper dies?"  JKR was 
surprised that this question won the poll for which question she 
should answer, and so was I.  It seemed to me, before she answered 
the question, that there were only two choices:  Either the Fidelius 
Charm would be broken (and the secret would no longer be a secret) or 
the the Fidelius Charm would remain intact, in which case no one else 
would be let in on the secret, because there would be no one 
available to tell it to them. (To avoid spoilers, I won't say which 
option JKR said was correct.) 

I'm surprised people voted for this question, because the answer 
seems to hardly matter to the plot.  Dumbledore held the secret that 
12 Grimmauld Place is the Order HQ, but so what?  If the Order stays 
or if it moves makes little difference.  It moved out temporarily 
after Sirius died, anyway. 

Anyway, this has started me thinking about the Fidelius Charm.  We 
know that the Potters, Sirius, and Peter all knew where the Potters 
were, and all knew that Peter was the Secret Keeper (except for 
Harry, who was too young.) It's been implied in the books that no one 
else knew who the Secret Keeper was.  However, other people did know 
where the Potters were.  Hagrid at least must have known, because he 
was able to go to the ruins and rescue Harry.  

I *don't* like the idea that Dumbledore knew Peter was the Secret 
Keeper (and the Traitor), and yet pretended that Sirius was.  This 
would imply a level of dishonesty on Dumbledore's part that I think 
is highly out of character.  I also don't believe that Hagrid would 
know that Peter was the traitor, and yet pretend it was Sirius during 
the conversation with Fudge, Minerva, & Rosmerta at the Three 
Broomsticks.  (I'm not sure Hagrid could have put on such at act, 
even if he wanted too.) 

So, how could Dumbledore send Hagrid to rescue Harry, if neither of 
them knew that Peter was the Secret Keeper?  Well, we know that if 
the Secret Keeper send you a note with the secret written on it, then 
you know the secret.  (This is how Dumbledore informs Harry of the 
Order's HQ.)  So, perhaps Peter sent notes to Dumbledore & Hagrid, 
but they thought the notes were from Sirius.

the Potters were killed
