Well, remember that the Potato Famine was hugely influential on the cultural landscape of Ireland. During that time, the population fell by 2/5ths due to one million starvation deaths and millions more immigrants that fled the country. There would be far, far fewer Irish in the US if it weren't for the famine.

I'd wager that there's at least three chapters dedicated to that: the lead up to, the famine itself and the subsequent fall out.
