Hello George,
Sorry, I wasn't quoting from the grave itself but from the excellent booklet of Memorial Inscriptions for Mochdre published by the Montgomeryshire Genealogical Society. The inscription also records John's wife Rachel's death on 4 April 1876. Strangely, though, the parallel booklet of Burials 1813-78 refers to the burial of John Stephens of Congley (aged 48) on May 6 1847 (not 1848). Perhaps the stone was not erected until after his widow's death and a mistake was made about the year...
Best wishes, g.
