Galwegian Gaelic
George Buchanan, himself a Gaelic speaker, writing in 1575, reported that Gaelic was still spoken in Galloway. In the middle of the century, 1563–1566, an anonymous English military investigator reported that the people of Carrick "for the most part specke erishe".
Celts
Today, the term Celtic generally refers to the languages and respective cultures of Ireland, Scotland, Wales, Cornwall, the Isle of Man, and Brittany, also known as the Celtic nations. These are the regions where four Celtic languages are still spoken to some extent as mother tongues. The four are Irish Gaelic, Scottish Gaelic, Welsh, and Breton; plus two recent revivals, Cornish (one of the Brittonic languages) and Manx (one of the Goidelic languages). There are also attempts to reconstruct Cumbric, a Brittonic language from North West England and South West Scotland. Celtic regions of Continental Europe are those whose residents claim a Celtic heritage, but where no Celtic language has survived; these areas include the western Iberian Peninsula, i.e. Portugal and north-central Spain (Galicia, Asturias, Cantabria, Castile and León, Extremadura).
