On March 31, 1847, over four hundred starving men, women and children walked ten miles from Louisburgh, (Co. Mayo) over the mountains to Delphi Lodge where the Board of Guardians were meeting. Turned away without food, they set out to return home. As they passed by Doolough, a storm struck. Some of the poor unfortunates died of exposure, others, their bodies so light from lack of food, were blown into the lake. Doolough means the black lake (the sun seldom shines on the lake because of the mountains).
