This is from the Cemeteries of Burnside Township book, from SandS Genealogists. In Robinson Cemetery:
McCowan, Bernice; wife of Oren McCowan; Sept. 22, 1882 - June 7, 1963
McCowan, Oren; husband of Bernice McCowan; April 12, 1880 - April 27, 1945
McCowan, Joe L.; son of Oren and Bernice McCowan; 1914-1937
I hope this helps.
