Whiteside County Genealogical Society archives at the Sterling Public Library. President is Marilyn Anderson who is also Director of the Genealogy Dept. at the Sterling Public Library. She would probably be the most helpful. http://www1.youseemore.com/sterling/http://www1.youseemore.com/sterling/They have Cemetery Listings for all of Whiteside Co. cemeteries. She may know who the sexton is if it is still active.
