I expect that both the Ohio Historical Society in Columbus and the Ohio Genealogical Society in Bellville (near Mansfield) would be very interested in the journal. You can contact OHS through their website at
http://www.ohiohistory.org/about-us/contact/donate , and for OGS, I would suggest you contact Tom Neel, the library director, at
tn...@ogs.org . Even if you do not find the original, both might be interested in a copy of your scanned images.
Thanks for taking an interest in preserving this material.
