why Chicago?

A Tidbit of local history for myself:

The indigenous Potawatomi tribe called the marshes on which Chicago was later built "Checagou (prounounced 'She-Ka-Gan')," which translates to "wild onion" or "garlic." European explorers assigned the name to the Chicago River, followed by settlers' delegating it as the name of the city. Before Chicago's founding, the name of the river was spelled several ways, such as "Chetagu" or "Shikago."
