I am the Transcription Coordinator of SFBAJGS, and we are transcribing all the burials handled by Sinai Memorial Chapel in San Francisco. I have a copy of all the cards from their alphabetical index of burials. We have not gotten to "O," but reviewing the cards I see Curtis ONHAUS, buried on 20 November 1948 at Salem Memorial Park. He died at Mt. Zion Hospital in SF.
If you contact Sinai at 415-921-3636, they may have a more complete record.
Thank you for being a member of SFBAJGS!
