Lord Palmerston presided over Mullaghmore and North Sligo during the worst years of the Great Famine of the mid-19th century. During the summer and autumn of 1847, nine vessels, carrying over 2,000 persons left Sligo port with tenants evicted and "shovelled out" from his Sligo estates. They arrived in Canada half naked and totally destitute. The city of St. John in the Canadian province of New Brunswick had to take many of Palmerston's evicted tenants into care and, outraged, sent a scathing letter to Palmerston expressing regret and fury that he or his agents, ‘should have exposed such a numerous and distressed portion of his tenantry to the severity and privation of a New Brunswick winter ... unprovided with the common means of support, with broken down constitutions and almost in a state of nudity ... without regard to humanity or even common decency.’ The graves of many of these unfortunate victims can be seen today on the old quarantine station, now a museum, at Grosse Ille near Quebec.
