While we covered Tituba a bit in the latest issue (including pointing out that she was likely at least partially Native American and not some Voodoo priestess!), this article from Smithsonian magazine adds more detail than we had the space to include.  As a bonus, they include a good look at a copy of Tituba's testimony from 1692, which might let you know why you could need a skill check to read old documents:)
