There are several Fayette county, PA, St. Mary’s cemeteries listed on http://www.findagrave.com/cgi-bin/fg.cgi?page=csr&CScn=s...
However all the 1915Mar2 miners buried in the St. Mary’s cemetery in my file that I searched do not seem to be on find grave.com John Miller or Hobart Osborn were not listed on the printed cemetery list I have in my file. You may try this web site:http://search.ancestry.com/search/db.aspx?dbid=70734
“Billion Graves.com Burial Index”http://billiongraves.com/pages/search/
John Miller’s death record is on http://www.wvculture.org/vrr/va_dcresults.aspx?LastName=mill...
but it gives no burial information? I have not read the accident report, but were all the bodies recovered?
