Dunmaglass (Dun Mac-glais) is a locality in the Canadian province of Nova Scotia, located in Antigonish County. Formerly a small community, the use of the name as such was rescinded in 1976.[1] Formerly known as both "back settlement of Knoydart" and "Summerville", it was officially named in 1879 after Dunmaglass, Scotland, the home of its first settlers.[2]
