A site of execution

After my visit to the Post Office, I repaired to the Black Isle Bar for a small beer and a de-stress. I then moved on to the Old High Church graveyard. There were so many tourists there that I wondered if I should make a badge for myself saying “Unofficial Guide. Please ask.”
   Rather astoundingly someone did, a visitor wanting to know where the 'Jacobite Stones' were.  I know a little about this and no-one knows much more, so I showed him the musket ball dents in the church tower (pictured extra, ) and a gravestone in line with it, (pictured main) on which a marksman could have rested his rifle. The only thing that seems clear is that a number of Jacobite soldiers, possibly deserters from the British Army, were summarily executed here for treason in 1746, following the Battle of Culloden.
   Although there are different stories about it, there are no surviving records from the time. It seems to me that the only way to substantiate the stories would be to dig up the path alongside the church where the Jacobites were supposedly buried. It would be interesting, to say the least.
  PS  The sale of the church fell through last year when the chosen bidder could not produce sufficient funds. The graveyard is public property. So who owns the path?
