What is "domnonee"

Domnonée is the modern French form of Domnonia or Dumnonia ( Latin for " Devon"; ), a minor kingdom in northern Armorica ( Brittany) founded by British immigrants from Dumnonia ( Sub-Roman Devon) fleeing the Saxon invasions of Britain in the early Middle Ages. Headed by the same ruling family, it was variously separate or united with its motherland and its Latin name was used for both indiscriminately. The mainland territory of Devon included Trégor, Dol-de-Bretagne through to Goélo, and Penthièvre. Its early rulers are sometimes considered " princes" but seem to have successfully united Brittany and become high kings under Saint Judicaël in the mid-7th century.
