Thanks for the word breakdown.... I am reading the book of Welsh saints(800 I think) so it struck me that Mold was an "edge" place for Saxon/British, forgetting of course the Normans in the middle.
Also had just read a story about St.Beuno. Apparently, whilst out walking by the side of a river he heard a Saxon calling his hounds on the other bank, he rushed back to his monks, ordered them to put on their clothes and shoes and leave this place. For he had heard "an abominable strange language..." they have invaded this land and will keep it in ownership"
