Gene--this is what I can give you and others are welcome to add. In Sangamon Co. there is a Cooper Township, and in that township there is the town of Buck Hart. There are four known cemeteries in Cooper Township and the one that I see near Buck Hart is called Oak Hill aka Cooper Cemetery. The Sang. Co. Gen. Society has a book which list all four cemeteries. <A HREF="http://www.rootsweb.com/~ilsangam/scgs.htm">Sangamon County Genealogy Society</A> --Check the publication list and look for Cooper Township Cemeteries. Maybe one of the cemetery lists would help in your quest. Jan Gray SCGS-Cemetery Chair Springfield, Illinois gjgrayinc@aol.com
