In 1874, the California Colony of Indiana, an organized group of migrants from Indiana, established what would later become Pasadena. Soon after, with non-Indiana settlers joining the colony, residents organized themselves as an agricultural association and adopted the name "San Gabriel Orange Grove Association." In 1875, residents (or, rather, association stockholders) wanted a local post office of their own, so they voted for one of three choices to name the post office: "Indianola" (for the original group of Indiana transplants who established the colony), "Granada" (recognizing California’s Spanish roots), and “Pasadena” (a name from the language of the Native American Chippewa tribe in Michigan). The name chosen, "Pasadena," is credited to Dr. Thomas B. Elliot, who learned of the name from a friend working as a missionary among the Chippewa. "Pasadena" is loosely translated to “of the valley.” Although inaccurate, the popular interpretation of the name meaning “Crown of the Valley” continues to persist.
