Does anyone have any knowledge of a Sprague "country boy" who became a doctor and practiced in Metz and Nevada (Vernon County)? My ggggrandmother was Kissiah Hornback Johnston. She came from a large family which settled in Platte County, MO in the 1840's. Kissiah and her husband, an Irishman named William R. Johnston, settled along the Kansas-Missouri border in 1856 and lived in Bates County for the rest of their lives. William died sometime around 1894 (nearly 100 years old!) and Kissiah was still living near Hume in 1916. I think there's a good chance this Dr. Hornback may be related to her. Any clue?
