History of Scottish Gaelic
All surviving dialects are Highland and/or Hebridean dialects. Dialects of Lowland Gaelic have become defunct since the demise of Galwegian Gaelic, originally spoken in Galloway, which seems to have been the last Lowland dialect and which survived into the Modern Period. By the 18th century Lowland Gaelic had been largely replaced by Lowland Scots across much of Lowland Scotland. According to a reference in "The Carrick Covenanters " by James Crichton, the last place in the Lowlands where Scottish Gaelic was still spoken was the village of Barr in Carrick: only a few miles inland to the east of Girvan, but at one time very isolated. Crichton gives neither date nor details.
Gaeltacht
An area in southern County Londonderry centred on Slaghtneill ("Sleacht Néill") and Carntogher ("Carn Tóchair"), which had gone from being 50% Irish-speaking in 1901 to having only a few speakers by the end of the century, has seen a language revival since the setting up of a naíscoil in 1993 and a gaelscoil in 1994. In 2008 two local organisations launched a "strategy for the rebirth of the Gaeltacht", based on Irish-medium primary and secondary education. Speaking at the launch, Éamon Ó Cuív, the Republic's Minister for the Gaeltacht, said that the area was "an example to other areas all over Ireland which are working to reestablish Irish as a community language".
