There is a county history; it could have information about that period and location. Turner County Pioneer History, William H Stoddard, second edition. Freeman, SD: Pine Hill Press, 1975, 470 pp. There was also a newspaper in Parker: The New Era. They have on-line archives back to 1928. http://ner.stparchive.com/archives.php They have an old hard copy archive that goes back well into the 1800s, but it is probably not available. There may be some "look backs" in more recent issues that are on-line (e.g., 100 years ago, or 50 years ago)..
