Hello Deb
I have done a lot of research on John Campbell, and have travel to Lochcarron where a small band of Campbells still reside. John Campbell would be my great great great grandfather. There is a book located in the New Brunswick Provincial archives titled “ History of Miscou Island” by William Francis Ganong, that makes notable mention of a John Campbell as one of the first English settlers on the island. The manuscripts can be access on-line.
