Hi Ian
I had a check in the Premnay MIs, but I'm sorry to disappoint you  - there are no stones to those names you mention, I'm afraid. 
As to Fiddes ancestors - my great gandfather was Robert Fiddes, illeg. son of Ann Lamond and Robert Fiddes (allegedly).  He was born in Old Machar (Aberdeen).  His father was also illegitimate, but I know nothing of him but doubt that they were in Kincardine area, but you never know!
