Again?

The fact that The Boston Tea Party wasn't called the The Boston Tea Party until much later relates, in a sense, to Pocahontas (I can't believe I'm writing about her again, I was hoping we were done with her). Things were twisted and we're really not sure what is true and what is not. Obviously we know the Boston Tea Party did actually happen, who did it and why, but what we don't know is where the name came from. Just like Pocahontas, the origins are a little if-y. Now that we have 2 examples of uncertainty in well known historical events/people, it makes me wonder what other parts of history we have had drilled into our brains that may actually have sketchy information supporting it.
