I do not know of a California Death Index for older deaths. The only death for Miner I found is:
Daily Evening Bulletin, San Francisco, April 16, 1880 MINER - In this city April 15, Matilda, wife of Edgar Miner, a native of Minnesota, age -7 (not clear on age it may be 87.
Was Matilda's daughter Kate C. Newton and what was her husbands name?Matilda's husband who died in Indiana - what was his name?What was Hannah's name that died in Ohio?
