Even if such a comprehensive list existed, it would likely be difficult to search effectively without specific identifying information about the individual you are seeking.
To find information about a specific individual who might have been incarcerated at the Preston School of Industry, you would need to research using alternative methods, such as:
* California State Archives: Contact them directly and inquire about their holdings related to the Preston School of Industry. Be prepared to explain your research purpose and possibly provide identifying information about the individual you are seeking.
* County Records (relevant counties): Depending on the nature of their offense and subsequent court proceedings, records might exist in the county where the individual was originally sentenced.
* Newspapers.com and similar resources: Historical newspaper articles might mention inmates' names in connection with escapes, events at the school, or related court proceedings.
* Family History resources (Ancestry.com, FamilySearch, etc.): If you know the individual's name and family history, you may be able to find clues linking them to the institution through family records or obituaries.
Keep in mind that research into historical prison records can be time-consuming and may not yield results. The privacy of individuals, even deceased ones, needs to be respected.
