Hi Forfarian
Your info on Drums and Greens is really helpful. In the case of Drums of Muirake it's described as on a spur of Knock Hil - that fits perfectly.
The colour green may be the most likely for Greens of Burgie explanation, as the Burgie vicinity is not right on the coast, it's a north facing area gently sloping up to a minor ridge/hill (Califer Hill). The location crops up on a gravestone, 1856 "John Murray late Farmer, Greens of Burgie". His death certificate has place of death as "Hill of Burgie". Perhaps I'll try study the census enumerator's sequence and see if I can glean any clues from the adjacent households he visited.
Thanks for explaining who the Mr Murray, Banker is likely to be, and how those notes occurred. Murray being a very common name in these parts. I will look closer just in case there's a family connection.
Thanks everyone for all your help, I'm learning so much!
