I have no information as of yet, I do remember seeing in the cencus a John Fiddler who had 10 members in his household. I live on P.E.I. and will be at the archives and library within the next couple of weeks. I'll be sure to look for you. Also I'd be more than happy to follow up on any leads from this end. I too am researching Fidler/Fiddler. Mary Jane Fidler daughter of James Fiddler and Hannah Offer. James moved to New Brunswick and I suspect John was his brother. Check the provincial archives for New Brunswick.
