Some flag musings for a TL project.
The premise here is an amalgamation of the New England region and the then-Lower Canada (within its 1791 borders, albeit with the difference in having all of Labrador as part of its national territory) at minimum in a scenario where an independent New England republic (choose POD here) is joined with the Republic of Lower Canada resulting from a successful Patriote rebellion, creating a new country in the United States of New England and Lower Canada; in a scenario where New England "rejoins" the British Empire on New England's own terms in a union with Lower Canada and thus allows the monarchy to come back to New England, the Colonies of New Brunswick, Nova Scotia, and Prince Edward Island would be included (Newfoundland is excluded in both cases since it's still doing its own thing), leading to its eventual long-form name open to speculation. In both cases, though, since I'm assuming the capital would be in Québec City, much like the case of Mexico IOTL the short-form name would end up becoming "Quebec" (though other options are possible if the capital is elsewhere, such as "Concordia") for ease of convenience. The basis of the flag in this premise are the traditional flags of New England (in fact, a proposal I made a while back for a flag of New England, combining the blue and partial outline of the Bunker Hill flag - although believed to be a printer's error - and the traditional flag of New England, in all its glorious red). In each idea, I'm using the version with the OTL Quebec coat of arms (for demo purposes) as the state flag and the version without the coat of arms as the civil flag.
