'An tOcras Mór' The Great Hunger.

My name is Jessica.  I have loved my Irish heritage ever since I found out about it.  I didn't hear about what went on from 1845 to 1850/51 until I was in college in the summer of 2010.  I was appalled when I learned that what I was taught wasn't the truth.  So I set out to find out what really happened and was shocked at what I'd found.  I had always known that there was tension between the Irish and English but never really knew why other than other events in history, but this really took me by surpise.  I am an aspiring screenwriter and have decided to write a screenplay about what really went on.  Although based on historical accounts, the characters- as far as I know, are fictional.  I want it to be as histrorically accurate as possible so I greatly welcome any information that can be given whatsoever.
