This isn't quite what I had in mind... but until I can figure things out, you may download this pdf which gives the names, dates of birth and death (if known) and whether a stone is extant or not. This is my own compilation from various sources including all of the following.
This record was submitted by Mrs. Brothers to the South Bend Area Genealogical Society, and is her transcription of the original Latin record books. She admits that there are errors on her part because of the difficulty of translating the records. Also, it seems problematic in other respects in that it includes many people for whom there are no stones, leaves out many who had stones in place during the same time period and includes people who are definitely buried elsewhere. Take it for what its worth. In merging the pdf files, it lopped off the top line on page 3: HAND, Joannes, Jan. 2, 1880 - 51 yrs.
I found this among our cemetery records. It does not say who the author was or any other source data. It may just be another transcription from the stones themselves, although some of the stones no longer exist. Many spelling errors. Once again, in merging the files, it eliminated the final line on page one, which reads: Loshbaugh, John A. d. May 3, 1853, ae 50 yrs.
