I guess Hermione and Ron had to know that Snape gave Harry his memories, as they were there. Did Harry (or any of them) tell anyone else that Snape gave him memories to watch (experience?)? And if so, did he tell anyone (even Ron or Hermione) what was in them, what he saw? I'm pretty sure it wasn't mentioned (directly at least) in the book.
I'm sure he made sure that everyone knew that Snape was, in fact, on their side, and probably even that he was highly instrumental in Voldemort's downfall. I'm more wondering whether Harry told anyone how he knew, i.e. through Snape's own memories, and if so, did he reveal anything more specific about what the memories contained?
