I checked a couple of obituaries at the library today and I am not sure of this is what you are looking for or not. The only Campbell that I could find that died on Oct 4, 1952 was a Nora Campbell who was born Aug 15, 1872 in Vernon Indiana. Her parents were Wales and Louise Campbell. Nora never married and was survied by a sister Margaret. As for Mary Copeland she died in a nursing home in Columbus, Indiana. Also there is no Washington street in Seymour but there is in Columbus so I think your Kenneth lived in Columbus and not Seymour. This Mary was born in Tennessee on July 1, 1886 the daughter of James and Cynthia Newberry Copeland. No immediate survivors were listed and she had lived in Seymour about 30 years. Hope this makes some sense to you.
