Sorry to relay bad news on this one. If someone in your tree has this posted, it would be because they recieved it thru family passing it down. Maybe contact them and offer to pay for a copy if they are willing to do it.
The bad news is which most people did not know is that in 1870 Dodge county courthouse had a fire that destroyed all records. This is horrible. I have been looking to verify my ancestors and live here in Dodge county. I asked the ladies there and the records where never kept anywhere else. so therefore no matter how hard we look for them, we just will never get them.
the only other way to find some information on the marriage would be directly thru the church where they were married. They usually keep them records at the church. That is currently what I am looking for, since I will not get them thru the court anymore.
