Hi Revae, If you haven't already received this info, here's who to contact. First the State of CA didn't require death certs until 1905 and then it wasn't strictly enforced. I looked for them in the pre-1905 death records but Santa Clara Co. hasn't been transcribed yet.
Contact Random Acts Genealogical Kindness for a volunteer to look them up in the Death Index 1905-2000. Go to raogk.org, read guidelines, choose California, choose ALL for County and choose Kathy or Margaret.
OR Contact the Santa Clara County Historical & Genealogical Society, scchgs.org/main/service.html who does research. Successful Searching!
