The original inhabitants of Ireland and Great Britain were a darker complected, more Mediterranean looking rather than Nordic type. They are believed to have come to the British Isles from Iberia in prehistoric times and modern genetic studies support this theory. The Irish, Scots and Welsh tend to have higher frequencies of dark hair and eyes and general overall darker complection than the English because the English have more Germanic/Nordic admixture in the genepool from the Saxons, Normans, and what not.     Many people also believe that the original inhabitants of not only the British Isles. but all of Europe were in very ancient times a darker complected Mediterranean type and not Nordic, and that the Nordic Aryans came into Europe from the East, from the Caucasus, from the mountains and steppes of Western and Central Asia....... just a theory.
