What did Mr. Cook mean by indigenous?. Let us not forget that the Scots were a marauding tribe from Ireland. That the southern part of what is now Scotland to above Edinburgh was once part of the Kingdom of Northumberland and that the Celts were a tribe from Spain. As far as I know nothing is known about "The ancient Britons" that we read about in history books... i.e the people that were here before all we settlers/vikings/romans/spongers etc got here.
