I checked today at the library - could not find an obit for either Mary Ann or William. It will be about two weeks before I can spend anymore time on this, so if someone wants to contact the south county newspapers feel free. Neither one appears in the genealogical society's index of county cemeteries. The Oregon Death Index has a Mary A Rice who died 27 April 1922 in Douglas county, Oregon. This is probably her. W.M. Rice appears several time in the index for the Plaindealer, but there's no obit listed. A tree on Ancestry shows his dod as 30 March 1895.
