POTC 4 spoiler alert

[Midhav]

What do you mean Teach's daughter is fake? She's one of the leading characters for the 4th film, check on ANY site. The part in his background where it talks about him escaping with his daughter Angelica is not intended as a historical fact. I just went to one of the talk pages on that wiki (Edward Teach, PotC4 or something else).. where my fellow users there (yes I'm one of the users) were discussing about the same thing. They gave these two comparisons:
*In real life, Edward Teach had 14 wives
*In the Pirates series Edward Teach has 14 wives and one daughter.
I don't get what "rescuing his ship" you're talking about, so please tell me (sorry)
Anyway, I'll just consult a few people on it, but I'm pretty sure that the reference would be to either "The Secret Files of the East India Trading Company" OR "Pirates of the Caribbean:The Complete Visual Guide". But what makes YOU so certain that Blackbeard came in the third film? The story about OST is that Ed and his daughter has been hiding in the Inlet for many years (or a few) and now want to come out to find the Fountain of Youth, as I have read in some sites.
