Question about the fact L.V. and Harry's wands are brothers?

I have just been enjoying reading the books again, even though 
everybody has been making fun of me (oh well) but something strange 
hit me today while I was rereading CoS... how does Mr. Ollivander 
know that both Harry and L.V.'s wands are brothers.  I know that in 
CoS Dumbledore and Harry talk about what happened to him in the 
Chamber w/ Tom Riddle, and Dumbledore does state, "Very few people 
know that LV was once called TR" (CoS page 329 hardback US edition)  
I guess I'm just trying to find out who knew and if Dumbledore knows 
that then, why doesn't he bring it up that if the two wands were to 
meet (which they do in GoF) what would happen and how does Ollivander 
know about the two wands, I began to think, while reading CoS again 
if when LV went after baby Harry he left behind the wand, but then how
could he have had it when he goes after Harry in GoF.  I guess since 
I have read and reread and reread these books over and over again, 
I'm now looking really close for clues, probably since I can NOT wait 
for the new book.  Hey JKR, we're waiting.  

On another note....for those of you who haven't read today's USA 
Today's Life section... there's a itty bitty bit on HP and JKR 
reveling HP's future.  It states, JKR says there will be love and 
death.  OoP is due out in 2002 (like we didn't know that) and she 
states "More people are going to die.  And there's at least one death 
that's going to be horrible to write."  (direct quote from USA Today)

And yes, (according to USA Today) photos from HP2 were stolen from 
Leavesden Studios and WB is asking the press not to print them.  (I 
know that this is movie related, but it was all in the same bit)

If anybody has any ideas about how Ollivander knew or if any has any 
guesses, I would love to know.... :)

Talk to you later.
