Have you taken a look for your ancestors in the miscellaneous record books at the County Recorder’s Office? Just about anything can be in these books. I’ve found divorce decrees from out of state divorces, copies of medical licenses, and a few other non-typical items in these books. Anyone can pay to have anything recorded–which just means that a “legal” copy has or was made. Soldiers might have recorded their discharge at the local recorder’s office as well.
