Switzerland: location of grave in Davos

[bilsat]

Hi All.
 When I was a child when I was on holiday in Davos, Switzerland we stayed at the family hotel "The Davosahof" just up from the station.
There was an old woman who had lived there for many years and told us that she was royalty from a country that was lost during the 20th century reshuffle.
She had a name that sounded like "Chockmockjohn", She also told me that she didn't celebrate Xmas when we did but on 12th January.
She was buried in the small hillside graveyard just outside Davos whose name escapes me, I know we walked from Davos towards the "landwasser" and crossed it, its probably about 1-2miles away from the town....(this was over 45 years ago)
If anyone can find her grave could they please photograph it please?
