Mike I expirenced the same frustration. My great grandmother spent 33 years in that hole. I was able to retreive a portion of her records. They remain sealed for 75 years, but every 6 months I write for the next installment. At the California State archives Genevieve Troka has been very helpfull. You can contact her at:
