I am looking for information on John David YODER, b. 1839 in Indiana, according to the 1900 census. John David married Melvina LYON in Floyd Co., Iowa on April 18, 1858. In the 1860 census John David, Melvina and Ada Viola YODER are living in Floyd Co., Rock Grove Township, Iowa next to Melvina's parents, Benjamin and Sarah LYON and daughter, Ermina (Mina), and next to them are Melvina's sister and family, Alexander, Viola and Ida GALE. In the 1900 census, the Yoders and Gale families are living in Lockwood, Dade Co., MO. What happened to John David and Melvina Gale YODER after 1900?
