Funny I had just changed that Bretagne doesnt mean Little Britain afaik but it was called that by the British settlers in the early middle ages Or it might be that those British used a term meaning Little Britain which the French then adopted and which then changed to Bretagne over time I wouldnt be surprised After all were talking  years ago and words can change a lot over such a long time Come to think of it its quite surprising that the words Britain and Bretagne are still so much alike
