I'm writing from Canada. I wasn't sure where to post it- Western Isles?

I'm looking for information of MacKays that came from Skye or Isle of Skye.

My last branch is:

Donald MacKay- 1798 -Skye Scotland who immigrated to Stellarton Nova Scotia Canada in 1809 and them moved to Big Harbour Island, Cape Breton, NS in 1824. He married Susan Ann Jane Cameron- not sure if she is from Scotland or NS. He had Donald II (married Margaret MacLean), Alexander (married Ann MacLeod and Sarah Mackinnon), Elizabeth, John, Mary, Hugh Cameron.

If anyone has any information, let me know.
Thanks.
