Hello, I wanted to touch base with you so that you knew I was trying to help you. I did find 2 Joseph Cleveland Corns buried in Pike County Ohio along with Ruth Taylor and Michael. If you go on www.findagrave.com. You will find pictures of their headstones. You may or may not already have this information.
Also, Michael's obituary was printed in Springfield paper on October 2, 1973. I will be going there Thursday or Friday and obtain a copy of that for you. Hope this helps.
