I am trying to locate my great-grandfather's brother, John Cotton. John and his wife, Lida Vansickle Cotton were married in Edgar County, Illinois and moved to Trego County, Kansas. I have found the family in the 1900, 1910, 1920, and 1930 census. I would like to try and locate their obituaries or tombstone records. John and Lida had two children. Jessie married Walter Musgrave but did not appear to have any children. Russell also married but also did not seem to have any children according to the census records. Any help would be greatly appreciated.
