Elsie Cameron of Fortuna Humdboldt County CA

Looking for information on Elsie CAMERON (nee FACE) who died at 1705 N Street Fortuna.
She was a "widow" at the time of her death.
I would like to find out more about her, as believe she was married to Frederick CAMERON, who was a great Uncle. My great Grandfather Donald CAMERON was Frederick's uncle, but as far as I know they never had any contact. My great grandfather died in Queensland in 1920.
Both were born in Australia, and for reasons known only to them they went to Live in Canada & USA in or around 1918. I have found the family in the 1930 census records.
Living at Humboldt.
Any help would be very much appreciated.
