The name of the town derived from Potawatomi chief Mettaywah, who lived in the area before signing the 1833 Treaty of Chicago and being displaced to Kansas. The traveler Colbee reported visiting the chief's village near the Des Plaines River and eating pork, cakes fried in pork fat, and a corn and bean dish. Many Potawatomi returned to Illinois annually until the end of the nineteenth century to visit their burial grounds.
