When you post, include the date of birth of the person. It helps to locate other possible records. I "think" you are searching for Eugene Lloyd Donley, Sr., born 4 July 1856, died13 Dec 1941. Buried in Urbana, Dallas Co, MO.
I now have found your family tree which has the above information. You seem to have a good idea on how to find your information. The other "researcher" and I are in Washington State and can't resonably help.
