Susan L. Kelsey lived in the Sauganash neighborhood of Chicago on the site of Billy Caldwell’s former 1,600-acre reserve land received during the 1833 Treaty of Chicago. She found a bronze plaque signifying the boundary of historic Fort Dearborn and Caldwell’s Reserve and wanted to learn more about the history of Billy Caldwell, “Chief Sauganash.” Over the course of twenty-five years, Kelsey followed the trail of Caldwell through two countries, thirteen states, and thousands of miles, and met new friends along the journey, intersecting stories about Irish Native Americans and learning about the land we call America.
