Wade,
Sorry but no luck with the search for James Manson & his wife or David Manson in any of the indices I have. Very few tombstones are listed for burials in the late 1700's or early 1800's - perhaps they were not generally inscribed at that time or otherwise 200 years of Caithness weather has obliterated the markings. Certainly there are literally hundreds of Manson buried throughout the County but none that tie in to these dates.
