Excellent summary of the case. One thing which they didn’t mention is that she wanted to cook because it paid more than twice as much as doing laundry, and as a cook she infected and killed more than one laundress with typhoid. She didn’t just infect and sometimes kill those she worked for, but other workers, as well. She even infected and killed some in a hospital.
She came from a prosperous town in Ireland. This raises the question of if she migrated just like she fled her work in the USA each time there was an typhoid outbreak: https://en.wikipedia.org/wiki/Cookstown
