Cornouaille

Cornouaille is a historic region in Brittany, in northwest France. The name is the French equivalent for the Cornwall region of Britain. This can be explained by settlement of Cornouaille by migrant princes from Cornwall and the founding of the Bishopric of Cornouaille by ancient Saints from the Cornwall region. The two regions spoke a similar Celtic language which evolved into the Cornish language in Britain, and into a similar language, the Breton language across the English Channel in Brittany; both Breton and Cornish in turn are similar to Welsh.
