Thank you so much for your help. I know that the 1930 census is accurate and I have documentation for her marriage to Roy E. Chase, and her death was in Oregon in 1958 with my great grandfather listed as her spouse on it.
The information in the 1880 and 1900 census could be her. Unfortunately, to order a copy of her death certificate they require the full name of both her mother and father, which I do not have.
Also, I do not have the DOB of my grandmother's half brother Wesley Chase. I know that he was older then her and lived in either Oregon or Washington, because I remember meeting him.
