I am hoping I link into this line. William had a son John who married Margaret MacKay. I think this might be my great great grandfather.
My great grandfather was Daniel (Donald) Buchanan who was born "near" Sydney Nova Scotia in 1849/50 - his parents were John Buchanan and Margaret MacKay (from Daniel's marriage certificate). They moved to Goderich Ontario shortly after Daniel's birth. Do any of you have information about John and Margaret? Thanks.
