Yes, it was largely peaceful during the Famine in 1847 and onward - lots of Irish died while grains were exported from Ireland to the British Empire. Happy, happy, happy. And peaceful.
My people left Ireland in 1850. My ancestor was illiterate and very peaceful. Well done, England!
Ah yes, the first recorded example of biological warfare when evil English scientists developed potato blight to destroy their own farms in Ireland and punish their Irish workers. Sir Robert Peel was so disinterested in helping Irelands plight that all he did was repeal the corn laws and spend £100,000 buying in American maize to feed the starving, which at the time was the largest amount ever spent by a govt on aid to a natural disaster. As for your forebears illiteracy, he was in good company - literacy amongst farm workers was not considered much of a requirement anywhere 150 years ago.
