Hello Paul.
Not being an academic I have up to now relied on an excellent memory
[academics I understand are prone to take note of every small detail]

[1]----check out Edinburgh University's excavation of a burial mound at Wemyss, Fife.----- Wemyss, forby being a surname is also I understand, the pictish word for a cave.

[2]----early 19th. C. drought, Moray Firth, excavation for a well in the town of Burghead.

P.S.--for refs. to both I may, given time, be able to come up with    something from the back nos. of the journals of the proceedings of the Society of Antiquaries of Scotland.
