Hi Terry, The State of Oregon will not release birth certificates until 100 years after a person is born. Therefore, you won't be able to get that document to find out who his parents were.
You can contact the Modoc County Auditor/Recorder/Clerk/Elections office for a copy of his death certificate. Contact information can be found at www.modoccounty.us/index_files/Page501.htm or 530-233-6205.
His parents names will be included on the death certificate IF a family member or the person supplying information at time of death knew their names.
They MIGHT be included in his obituary. You can contact the Cedarville Branch, 530-279-2614, infopeople.org/modoc/location.html for a copy of his obituary. Successful Searching!
