The original Acadia in 1754. Click to ENLARGE. From Wikipedia.
Yes, my beloved ‘Acadia National Park‘ is related to the Acadians but semi-indirectly. The actual ‘Acadia‘, as can be seen from the above map, was further north, in Canada. But, the notion of calling that whole NE area ‘Acadia’ persisted.
Canada has a ‘National Acadian Day’. The Day After Thanksgiving holiday is restricted to Louisiana.
