Sc haddery + Sc loch
‘Heathery loch’, containing OSc haddery, hadry-, hadrie (DOST) ‘heathery, heather-covered’, referring to the predominant vegetation around the loch. Hadrieloch is consistently associated with Midmuir LEU (q.v.). Ainslie/Fife (1775) shows Heatheryknow at about NO477237 in what is now Tentsmuir Forest, the area formerly covered in lochs and marshes, and there is probably a connection between these two names which share the same specific.
The very approximate NGR is the km square between Old Moors (1855), and Heatheryknow (1775).
