I checked the Cemeteries of Butte County. no luck.
I looked in the index file for obituaries. And was able to find the death place of Clarissa Heath with a death certificate showing her parents to be May C Chisler and Sanford Forbush. Spouse Wm R Heath
I will post the Obituary in that area of these pages. Which will show where she died.

I have a book on the Forbush Families of Idaho. Complied by Harold Sanford Forbush. I can help with any questions you may have on the Forbush line. Please just email me. It would be too big to put as a response.
