Researching in Sacramento, Chico or Redding? I have the following and will do lookups for you:
History of Sacramento County with Biographical Sketches published in 1923. This has an index and short biographical information of "leading men and women of the county who have been identified with its growth and development from the early days to the present." Also has some pictures of individuals.
1928 Sacramento High School Yearbook 1929 Sacramento High School Yearbook 1938 McClatchy High School Yearbook 1965 Sacramento High School Yearbook 1966 Sacramento High School Yearbook 1968 Chico State College Yearbook 1969 Chico State College Yearbook (this one does not list graduates or identify most pictures in it) 1962-63 Enterprise High School Yearbook 1964 Enterprise High School Yearbook
I also have a copy of the program from Ed Smith's 23rd and F Streets Neighborhood Reunion from 1987 listing attendees. These are people who lived in the Sacramento neighborhood in the late 1920's and 1930's.
