Have you visited your State Archives? If you haven’t, you are missing a valuable resource for records concerning your ancestor.
The Indiana State Archives is in Indianapolis. The archives has a wonderful website, where some of the records are digital versions and searchable. Also, one can contact the archives with questions concerning your ancestor. They may even be able to copy records for you and either mail them or email them to you. I have contacted the Indiana archives with many questions, and they have always been very helpful. I have also visited there, and the archivists are very knowledgeable and helpful.
