From Britain or land of the Britons
Brytnee is a modern creative spelling of Brittany. It originally referred to the Celtic people who settled in the region of Brittany, France, and later Great Britain. This specific spelling variation gained some traction during the late 20th-century trend of replacing 'any' or 'any' endings with 'ee'.
