I found my gggg-grandfather William Persinger buried in Xenia Cemetery in 1854, on page 81 of this book:

Cemetery Records, Greene County, Ohio (table of contents):

Where is Xenia Cemetery now, or was this not the official name of the cemetery? I don't see a publication date on the book so I don't know when it was researched/written.
