 Stephens (1982:7)
 "I am a native speaker of the dialect of Bro-Dreger, having learned 
 French only when I went to school.
 Most of my study will be based on my experience with and knowledge of
 that dialect. I should remark, however, that I have examined sources 
 from all the other dalects including Bro-Wened. These are available in 
 a number of publications in Breton, such as Al Liamm, Hor Yezh, 
 Pobl Vreizh, Barr-Heol, Brud Nevez, Skrid, Al Lanv, Evit ar Brezhoneg.
 An important other source is the collection of the spoken Breton of 
 Bro-Dreger by Jules  Gros (1970, a, b, 1974). 
 Gros, himself a native speaker of the dialect of Bro-Dreger, carefully
 compiled a collection of Breton as it was spoken, in the first part of 
 this century [XX°]."
