According to History of the Ohio Falls Counties, published 1882, there is "An Old Graveyard" in Oregon Township which we have not yet identified except the following excerpted reference from page 374 that book:

AN OLD GRAVEYARD

"At the confluence of Dry Branch and Fourteen-mile creek is the oldest burying ground in Oregon township. No reliable information as to who were buried here first can be obtained. Trees, one foot in diameter, have grown on the graves; the bushes are thick and vigorous, and the briars in a healthy condition. There are no fences or tombstones. Every thing is in a dilapidated condition, and it seems as if Nature was left to take her course. The pioneers who rest here, certainly deserve some attention from those who are now enjoying the fruits of their labors."
