Afraid I do not know.I have written here whatever I do know. Canada411.com, or telus.com might give you descendants living in the provinces you are asking about.Or post to ancestry.com message board, re the family names you are researching.
There is a beautiful Canadian singer called Catherine McKinnon who is married to a Canadian Actor and writer, Don Harron.His character was Charlie Farquharson, on CBC.Try to google for him, or Catherine McKinnon.His wife is running a tea house maybe in the Maritime Provinces. northcountrychorus.org/maritimes.html
Lots of the McKinnon's were Lord Selkirk's settlers from Scotland.Google for Lord Selkirk's Settlers to the Maritimes. They were farmers I think.
Let me know if you have success as I have McKinnons in Ontario from Scotland also.
