Hi Dick, do you know where and when she was born? How sure are you about her maiden name of Vale?
You can order a copy of her death cert to find out her maiden name. Her death cert # is 13 which I think you'll need to order a copy. See www.oregon.gov/DHS/ph/chs/order/faqs.shtml for instuctions on how to order the death cert.
After you have verified her maiden name, her family should be fairly easy to find on the Census records. However, I don't see anything now under Vale. Successful Searching!
