Oh Im sorry to hear that.
Since the last post I did some more digging and found that one of the sisters, Mary Maggie, immigrated into Maine. I believe it was 1922 and she listed a "Neil" as her contact in there. I looked back and saw no Neil but a Heilly. When I looked at the Canadian 1911 census it was written in as Neilly but there must have been a transcript error and he became known as "Heilly" on here. Also on the boarder crossing papers it listed Donald, her father, as the Candian contact and he was now living in Halifax.
I think I will do a new McLellan post with the updated information as you suggested. Where do you think I should post it; in Inverness, Halifax or Maine?
