Hi Lynn, Was she adopted? For adoption information go to http://www.courtinfo.ca.gov/http://www.courtinfo.ca.gov/ . Seems like sometimes an adoptee can access info and other situations they need a lawyer.
When was she born? Was her surname Miller or a different surname?
I did find two Harold Miller's who lived in that part of California. The first was living in Redding, Shasta Co. in 1880 with his family. John H. Miller, b. MI, 37 yrs old, physician. Elizabeth, wife, b. France, 40. Charles H., b. PA, 8. Edward H., b. PA, 6. Harold, b. PA, 4. Ethel E., b. PA, 1. However, it appears the family moved away.
A Harold Miller and wife lived in Westwood, Lassen Co, CA in 1920. Harold J. Miller, b. CT, 25, sawyer lumber co. Gertrude O., wife, b. CA, 29, bookkeeper lumber co.
