"People from NB are correctly called "New Irish" because the original name of the place was "New Ireland." Or "Newmicks" or "Fenians Nouveaux."" I shall require references and sources for such. I believe such was proposed but never happened.

And it never should have happened. The First Nations of New Brunswick include the Mi'kmaq, Maliseet/Wolastoqiyuk and Passamaquoddy. If anything, NB should be called "The Land We Owned, and Still Own BTW, Before You White Assholes Fucked It Up for a Cheap $$$".
