Yes, like Tupka217 says, Elrond would know some of the origins of where the 9 rings went, but unlikely to know specifics. Supposedly Sauron (posing as Annatar at the time) stole the 9 rings from Celebrimbor and perhaps only he knew who they were given to. Most of the elves had very little contact with a bulk of the tribes of men except for the Numenoreans and their descendants.
