Going to River View Cemetery in Portland, Oregon. I found Mr. & Mrs. Reeves are buried in section #125. Mary E. Reeves was born 2 March 1895, date of death 31 Oct. 1975. Mr. Reeves marker states, "Orian S. Reeves" under which it is engraved 1881 "BALDY" 1961. Hope, this is helpful.
i could not find an obit for Mr.Reeves, however you can always try the Funeral Home, or the Cemetery , and ask for a copy. If you have no success with that my suggestion would be to pay University of Oregon Libraries to research the death information for you. Good Luck!
