Neil the Middleton'strain book is crap, the old Middleton terriers were good i have old midd lines in mine , we can disect the back ground of every line , and ill repeat the question i asked Gary at the Yorkshire when did you put welsh in your line , never got answered mind, , so its back to what Ive said a hundred times, lines are only as good as the memory of the person who bred the terrier and the records kept , and the people who they obtained there stock off in the first place, old photos can be looked at to compare todays lines look at the photos of midds old stuff in that book and other
