Need Help Obtaining Obituary

I would greatly appreciate help in obtaining an obituary for my great uncle. His name was Harry Baker. He last lived in Vista, CA. He died in San Diego County 19 April 1975. Someone looked for me once but didn't have access to the right newspaper.

Harry is one of the mystery men in the family. He was adopted and his birth surname was O'Brien. My great-grandparents were living in Paulding County, Ohio when they took him in. The family moved to Kalamazoo County in Michigan in 1909.

Thanks very much.
