I'm looking for an obit for Dora Ogden. She was in the Eastern Oregon State Hospital for the 1920 and 1930 census, and then I don't find her until a death listing in 1974. It has her date of death as Sept. 2, 1974 in Terrebonne. She is my great-grandmother.
Because she had been in a state hospital, I'm not sure if I can even access any records to know why she had been there, but hope some kind of death record or obit could help.
Any tips on how to proceed?
