Joseph J. Jameson was was born 17 Oct 1867 in Kansas, the son of Zenas Dexter Jameson and Christina Elizabeth Smalley.

On the 1910 census he is listed as James J. Jameson and is living in Salina, Mayes County, Oklahoma with wife Cynthia and children Cecil, Henry, James, and Orval. On the 1920 census, in Salina, Mayes County, OK, his wife is listed as a widow with children Cecil, Henry H., James J., Orvil M. and Alta.

My questions are where would I locate a death record index in Mayes County for the period of 1910 to 1920 in order to find his date of death?
Once I get the death date where would I locate newspapers for that time period in order to locate a death notice? What organization is keeper of cemetery records in Mayes County so perhaps I can find his burial place thus getting his death date that way?

Thanks in advance for any assistance!
