Thank you very much for checking both, Donna. James was her husband. I was a bit surprised there was no stone. It reminded me of a discussion on this board back in, let's see, May 2005 about MIs for DBC - Kay spotted an apparent gap between B342 & B354 that seemed to have perhaps been omitted from the binding. I don't know the layout of the cemetery, but could A343-5 be in the same area? I'm speculating they could have been transcribed at the same time by the same person and somehow their work was left out? I wonder if there are stones for C343-5 listed.
Flight of frustrated fancy! Thanks anyway for your trouble.
