Though not widely remembered today - at one point Saint Cornelius of Ireland (not to be confused with Saint Cornelius of Antioch) was second in popularity in the Emerald Isle only to Saint Patrick.
Saint Patrick is remembered for driving the snakes out of Ireland. Saint Cornelius was said to have driven the squirrels out of Ireland. This "miracle" of Saint Cornelius later proved to be his undoing. During the Great Potato Famine starving Irishmen and women wished they had tasty squirrel meat to eat and they cursed Saint Cornelius for driving out the furry rodents. In response to this outrage - Pope Pius IX removed Cornelius from the roll of official Catholic Saints.
