Yup, good writing. And I've always said Argentine.
When my great-(however many times)-grandfather left Ireland for the USA at the time of the potato famine, he had brothers who instead went to "the Argentine". But we've never been sure whether that really meant Argentina specifically, or whether they just used that as a general term for South America, as I seriously doubt their grasp of geography was very good.
At any rate, I should have distant cousins here somewhere, but with Bryan being such a common Irish name, good luck ever tracking them down.
