We're leaving how much you want your characters to recognize the pirate names up to you guys, whether they know accurate specifics, or wild rumors, or have never heard of them at all. But this is a bit of dialogue from a canon scene, between one of the Nassau pirates and a random teenage girl who's never left the mainland and just knows about pirates through local news. I imagine someone with government or military connections would have more accurate info, but if you're not sure about average peeps, here's a good example for everyday gossip —

GIRL: Is it true?
JACK: I'm sorry?
GIRL: Uh, is it true that you've come from Nassau? It's true, isn't it? You're one of them. You're a pirate. You are! [chuckles] I hear everyone knows everyone there, even the giants. Will you tell me, did you know Edward Teach?
JACK: Yeah. [chuckles]
GIRL: And Jack Rackham? Did you know him, too? I heard a story that Jack Rackham outsmarted Captain Flint to capture a Spanish treasure galleon right out from under him.
JACK: Yeah. Knew him, too. And believe it or not, that story is true.
GIRL: What about Charles Vane?
JACK: Charles Vane was my closest friend in the world.
GIRL: Tell me everything about him.
JACK: He was the bravest man I ever knew. Not without fear, just unwilling to let it diminish him. And loyal to a fault. And in a world where honesty is so regularly and casually disregarded —
GIRL: I heard he cut off a man's head and left it as a marker in the sand to anyone who would cross him.
JACK: It was a little more complicated than that.
GIRL: I heard - he sometimes butchered his enemies for amusement, made stew of their flesh. He was truly an animal.
JACK: Stew?
GIRL: Mm-hmm.
JACK: For what possible—, I'm— I beg your pardon, but do you believe this?
GIRL: I read it in a newspaper.
JACK: Oh.
SERVANT: Mr. Guthrie will see you now.
JACK: Charles Vane was a good man. What I told you was the truth. Put down the newspapers and read a book.
GIRL: [scoffs] Truth isn't nearly as interesting.
