What 3 stories can I read to get information on Puritan Theology?

I'm studying American Literature and we have to write just one paper on Puritan Theology. I know Mary Rowlandson, Anne Bradstreet and Johnathon Edwards. Do these sound good? I have read these stories awhile ago and just don't want to waste my time going back over them if anyone thinks there is something better to read. Many thanks!!!!
