Archaelogists have discovered evidence that some people in the borderlands of England may be descended from Moors from northern Africa, Roman soldiers brought over to guard Hadrian’s wall. One more interesting ingredient to the mix of Picts, Saxons et al.
Also a little ironic, considering that many of these people are the so-called Scots-Irish who settled much of Appalachia and the American south, with its slavery and anti-miscegany laws.
