need help with an american lit paper due tonight.

I need to turn in  a paper by tonight. 1100-1300 word (6-8 typed, double-spaced pages) . Jacobs' Incidents in the Life of a Slave Girl was considered totally fictitious until the early 1980s, when researchers found documentary evidence in the North Carolina State Archives supporting the facts of the story. Apparently, the major change made by Jacobs involved names (e.g., fictitious Linda Brent = real Jacobs; Flint = real Norcom). Explain how the story seems either fictitious or real.
