You need to check out "Hattie Family Memoirs", pages 251-256. It has tons of info on John Dewar (born in Perthshire), who arrived in Nova Scotia, Canada in 1803. It also mentions his children and their children. I got the book at my local library (they had to bring it in from another library branch).
His wife Rebecca had a sister who married my relative Gregor McGregor. There are several families (McGregors, Hatties/McHatties and Dewars) that are linked through marriages as many of them came from the same area in Scotland, and several of the men served in the British military and were awarded land grants close to each other. Hopefully this will help in your research.
Happy Researching!!
