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".
Celtic Revival
The Gaulish language used to be widely spoken in France and beyond. In recent times there have been attempts at revivals, despite very limited evidence for the exact original form of the language. Eluveitie is a metal band whom most of their songs are in a revived Gaulish.
