Dear Ms. LeDonne,
Thank you for posting your request on History Hub!
The location of any court records depend on which court the case was tried in. If it was tried in a federal court, there may be records of the case at the National Archives at Chicago (RM-CH). Please contact RM-CH via email at email@example.com.
Due to the COVID-19 pandemic and pursuant to guidance received from the Office of Management and Budget (OMB), NARA has adjusted its normal operations to balance the need of completing its mission-critical work while also adhering to the recommended social distancing for the safety of NARA staff. As a result of this re-prioritization of activities, you may experience a delay in receiving an initial acknowledgement as well as a substantive response to your reference request from RM-CH. We apologize for this inconvenience and appreciate your understanding and patience.
If it was a state case, we suggest that you begin your research by contacting the Clerk of the Circuit Court of Cook County Archives Department.
We hope this is helpful. Best of luck with your family research!
I assume that you do not know the court where the case took place, so I suggest you start by searching for the names of people involved in Chicago newspapers in the 1960's in order to determine which court. Then contact the court to ask where the records for that case are currently stored.
