re correction to TomTomson's comments from last Thursday- "Northwards, [from
Perthshire] it [Scottish Gaidhlig] was spoken pretty well everywhere but
Actually including Caithness, at least the western part. Much of the area
west of Thurso contains pure Gaidhlig nomenclature, sometimes even in the
proper spelling suggesting Gaidhlig may have been spoken there when the
cartographers came along. Links follow the next paragraph.
In the eastern parts the situation is more complicated, the question being
when did Gaidhlig die out, and was it before or after the Norse invasion?
Certainly I believe Duncansby is a Scottish Gaelic name, but a very old one
(it may appear in the Orkneyinga Saga itself) and pre-Norse invasion. If it
wasn't wiped out entirely by the Norse, or was reintroduced after the Norse
settlement, the big question is when did it die?
[All spellings as on map]
North of Lybster and Latheronwheel is the name "Cnoc an Earranaich", as well
as Achavanich. Both of these are well within Caithness. Unfortunately the
boundary is not marked properly to the west where there are many names in
Gaidhlig spelling. There are certainly more like the above example.
