The Sir Francis Bacon Theory started with Mark Twain's autobiography, Is Shakespeare dead?
You can find it online at project guttenberg.
It's covered in this docuмentary The Secret History of America's Beginnings part 14 and 15
The folks who made this docuмentary are very ant-Catholic and really only present one side of the argument. There was a good BBC program on Shakespeare's life.

I've ordered The True Face of William ShakesPeare, will summarize when I get a chance to read it.
