I am afraid in my youth I was the witness to Gaelic slipping away in the rural community I grew up in. My Grandfather was a Scottish immigrant, a native speaker and a Presbyterian Minister. I understand that this was considered a real asset early in his career as many communities desired Gaelic services however the demand slowly died out. He served several small rural churches and I think gave his last services in Gaelic in the late 50's. I believe those would have been at the small congregations at the north end of Victoria County in central Ontario in the villages of Cameron, Argyle, Glenarm and Kirkfield. As a boy I do remember him conversing in Gaelic with older people after the service but not using it in Church.
