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.
Braemar
In the 1891 census, 59.2% of the population of Braemar spoke the Gaelic language "habitually", the percentage of those actually able to speak the language (despite not having much opportunity to) would have been somewhat higher. The small crofting township of Inverey ("Inbhir Èidh") was 86.3% Gaelic-speaking, most non-speakers being originally from Lower Deeside. The Gaelic spoken in the Aberdeenshire Highlands shared most features in common with the Gaelic of Strathspey and East Perthshire. The last native-speaker of the local Gaelic dialect died in 1984, though there are still surviving native-speakers of the similar Strathspey dialect.
At the 2001 census, out of a total population of 839 in Crathie and Braemar Civil Parish, only 5 (0.6%) claimed to be Gaelic-speakers.
