I sure wish I had some mental kind of visual puzzle-piece grouping to show me when the Picts and the Gaelics and the Anglo-Saxons and the Celts are were--and where overlapped. It is very, very confusing. All I do know is I love the man whom William the Conqueror conquered--and wish he had won if only because he so valliantly went from one huge battle, a victor, on, exhausted, to try to fight William.
