The problem with divorces is that they may become contentious, and so are most often kept confidential for 100 years or more. The records are likely kept in the Monroe County Clerk's Office, and one would have to go there in person to get the case number. At that point, you could ask to see the files. You might get to see them, or you might not. We just looked at that citation and it's pretty bare bones.
