Alexander and Thomas Campbell, the first missionaries in the Bethany area.
A two and a half foot thick stone wall, erected from stones from taken from two local old flour mills, was added in 1866, after the death of Alexander. It is said that because of this wall, the souls of the those laid to rest are trapped in the cemetery, resulting in an eerie presence that permeates the entire place.
UPDATE February 2012: It seems as if the people of The Wheeling Inn loved my blurb about this cemetery so much, that they added it, word for word, to their own website, lol. It was time to do a little more research on this location, anyway...
