I hear what you are saying!
I got some 'family tree' info, on my MacNaughton ancestors, last year. Robert MacNaughton, born in Scotland about 1776; emigrated to Canada, with his family, and settled in Dalesville Quebec, about 1824. Following the family tree, there are now thousands of descendants ( or maybe 10's of 1000s?). No doubt, this why we hear that thre more people of scottish descent living outside of Scotland, than Scot living inside of Scotland - and more than lived in Scotland at the time of the '74.
