In this lecture, attendees will explore the unique historical and geographical factors that shaped the records of the Sunflower State. The session provides a methodical overview of Kansas’s transition from Native American territory and part of the Louisiana Purchase to a focal point for pioneers seeking farming and homesteading opportunities. Participants will learn how to navigate the complexities of “Bleeding Kansas” and the territorial period, as well as how to utilize state-specific resources such as the Kansas State Census (conducted in years ending in “5”), internal migration records like the Orphan Train complex, and specialized digital archives like Kansas Memory. By examining the impact of the Homestead Act and the diverse ethnic groups that settled the region, researchers will gain a comprehensive framework for locating ancestors within the rich manuscript and vital record collections of the Great Plains.
