Devon Bunkers are from an earlier migration to England than the Beds Bunkers who may have come from Normandy, Although the Bon Couer spelling comes up occasionally in the Beds Bunkers, I have never seen it among the Devon Bunkers. DNA testing is highly unlikely to come up with French or Viking ancestry among the Devon Bunkers. I like to think of the Devon Bunkers as Celts but those of you who know your history know that the so-called Celts were many different groups of people. Maybe the Devon Bunkers were among one of them. It would be interesting to find out wouldn't it? Bette
