This will be a long shot but I am trying to move one step backwards to another generation, I have Dunn's in Colchester county Nova Scotia and in the census they are listed as Scottish as their orgin, I would think in the 1790's is the most likely time that they would have come to Canada and probably into Pictou County, this is of course speculation but who knows I might just hit the jackpot, the name that interests me most would be a John or James or John James Dunn, if there is anyone that can add anything, please contact me at Jennill@cogeco.ca Thanks Kim Barlow
