Dear Ms. Anders,
Thank you for posting your follow up inquiry to History Hub.
It is possible that the Iowa State Archives may have additional information on a state court case, however, you will need to contact that archives directly for more information. The majority of the records should be held within the court system, however.
The National Archives holds U.S. Federal Court records created by Federal district courts, Federal circuit courts, Federal courts of appeal, and the Supreme Court. If you believe part of the case was tried within the federal court system, please contact the National Archives at Kansas City at firstname.lastname@example.org. There is no index available online to check for court cases in the collection; a staff member at that location will need to search their internal databases to provide more information.
We hope this information is helpful.
