Hoping to find where Steven Bull (son of Samuel Bull and Marcia West) and Catherine (Cronk) Bull died.  I have their dates of death as: Steven in 1887 & Catherine in 1892.  They are both buried in Wildwood Cemetery in Chesaning, Saginaw County Michigan.  I have not been able to find them in any death record search in Saginaw and Genesee counties, familysearch.org and I even looked in Marshall County, Iowa where they were living with their son Alonzo in 1880. I know people assume since they are buried in Michigan they died here, but I can't assume.  Seems odd I cannot find any original record of their death. Michigan began recording deaths in 1867.  Help!
