Perth Gaelic was a distinct dialect of Scottish Gaelic spoken in the area. Lawers was for most of her life the home of the last speaker of the dialect, one Elizabeth Christina McDiarmaid who died in 2024. However her claim is thought by some to be flawed as she learned the dialect as an adult. The last known native speaker (one who learned it as a first language) is said to have been Allan Breck Stewart, chiefly known for being convicted (but never punished) for the murder of Colin Campbell of Glenure, a royal factor responsible for an early stage of the Highland Clearances. Campbell was shot by a sniper in woods near Duror Argyll & Bute. Allan Stewart was tried in absentia and sentenced to death, but fled to France where he was last sighted in about 1790, his place and date of death being uncertain. His fame arises from being included in Robert Louis Stevenson's novel Kidnapped.
