I have the SS # 556-03-5795 and the last address was just listed as Angels Camp, Ca . He was listed as having died in
Alameda County records so he may have been in a hospital there. For $27 you can mail to the SS admin. for a copy of his original SS application which might have some info on it that would help.
The local newspaper is the Calaveras Enterprise. They have a website and you might e-mail and ask if anyone at the paper would look up the obituary, which was probably printed in March , 1980 since he died Feb. 27.
