There is no doubt that "Trevellyans corn" refers to the Maize imported for "famine Relief", even though it is more accurate to point out that that Trevellyans policy was to encourage the Irish free market to solve the issue of famine, and he locked up the imported maize that was there and turned away fresh shipments.

It should also be noted, that unlike famine relief today, victims of famine had to buy their corn - a slightly disingenuous form of relief, as they would happily have bought food if they had had money in the first place.

The whole event is a perfect example of the realities of laissez faire/ trickle down economics at its most callous, not to mention the myopic total lack of comprehension from the public school educated millionaires who took turns at running the British Government at the time.
