Thank you for that. Yes, that's the name I was told about; now that you mention it, I remember.
Nice to know he's still around.
If anyone knows how to contact him, or his full name, please send me a PM. I know that someone in my family worked with him about 15 years ago. It would be nice just to meet him; it seems like he's a legend in his own time! I have the sense that my predecessor may have exhausted what was knowable, but I am not sure, as techniques are different now. I would like to at least see the farms in question, which I have found on the modern OS.
It certainly is remote! I looked into getting there once on a previous trip and decided against it. As I recall, it was one bus a day that went there, maybe less than that, and it wasn't at all clear to me where I would be let off, or what I would do if I somehow missed the bus on the way back, or how I would get around once I got there! So I decided to put it off until I had some company, and probably a car. But that meant that I missed Murdo, alas.
