The library has many old records, as does the OSU one. If you go to either library and have no luck, I'm sure the librarians would have more ideas for you. This sounds really interesting and I'm glad you are looking into your family's history. I love that kind of thing. Good luck with the search!
If you have already tried the museum, try the library for any historical items from the county. You might check the library at OSU, or any geneological group in town
