I am also looking for records on the Jochim family. I have had a lot of luck using familysearch.org. I don't know if you have tried this. I have been able to get birth records going back to 1870's and death records. If you haven't tried this and would like to know how to search I would be more than happy to direct you. I have the original copies of certificates which comes from LDS and got them within 3 weeks.
