Mary Jo, do you subscribe to Ancestry.com? I found two Caroline SCHNEIDERs in the 1880 Census, one for Franklin Co. and one for Morgan Co. OH. However, it is entirely possible that the surname "Schneider" was spelt "Snider" or "Snyder" by the census taker. This happened to my ancestors in Fairfield Co. I did find quite a bit on your Jacob Friednauer, though. That looks like an interesting story!
