I'm a Nova Scotian (born to Nova Scotian parents in North York, Ontario and raised from Grade 1-12 in Chicago, but Nova Scotian nonetheless, and in Halifax now) and I had never heard of Nova Scotia being referred to as "The 14th Colony," though I do suppose it makes sense.
My own family (father's side, my surname)came to the North American colonies in 1634 from England to Boston, later going to New Hampshire, then to Nova Scotia to fight at Louisbourg and finally settling on land grants around Truro where the family farm still is today (with my Louisbourg ancestor's officer's sword on the mantel).
Growing up in the States with summers in Nova Scotia made the differences between us and the similarities between my Canadian family and my American friends very clear and hard to describe to one side or the other.
Always the proud Canadian in school or work in the States, yet always the first to defend the States from ignorant comments from my Canadian friends in university in Ontario, I love both countries and feel at home in either one, though Canada (particularly Nova Scotia) is and always will be my home... At heart if not physically!
Here's to 200 years of much more congenial cross-border relations... Yankees, I salute you! After all, if it weren't for me Anglo-Saxon English forbears' love of fighting the French, I'd be a New Englander!
