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".
Galwegian Gaelic
The likely eastern limit reached by the language was the River Annan, for the reason that Gaelic placenames disappear quite rapidly beyond this boundary. In the north it was possibly cut off from other Scottish dialects in the 14th, if not the 13th century.
