When I have questions of this sort I usually turn to Streetmap. After a little creative searching, I'm guessing the place you're looking for is what appears to be a single building named "Dherue" or "Dithreibh", located just south of Loch an Dherue, a.k.a. Loch an Dithreibh, a.k.a. Loch an Dherve, itself located south-southwest of the Kyle of Tongue. There is also a steep hill to the east of the loch named Creag an Dherue, or Creag an Dithreibh. Also south of the loch are a stream named Allt an Dithreibh and a valley named Srath an Dithreibh. The name probably comes from děthreabh, meaning "desert", "unihabited", "uncultivated", etc.
