Laura Secord is not only the name of a Canadian brand of chocolates, but also a Canadian cultural icon. In the War of 1812 she overheard some American officers who had commandeered her farm planning an attack on the British. After a grueling, perilous journey cross-country she succeeded in warning the British commander, Fitzgibbon, and saved the day. There's more about the story (well-known and loved by Canadians-one of the few stories treasured for the come-uppance of Americans) at:
