English, Irish, Scots all come from the same stock apparently
Britain and Ireland are so thoroughly divided in their histories that there is no single word to refer to the inhabitants of both islands. Historians teach that they are mostly descended from different peoples: the Irish from the Celts, and the English from the Anglo-Saxons who invaded from northern Europe and drove the Celts to the country’s western and northern fringes.
But geneticists who have tested DNA throughout the British Isles are edging toward a different conclusion. Many are struck by the overall genetic similarities, leading some to claim that both Britain and Ireland have been inhabited for thousands of years by a single people that have remained in the majority, with only minor additions from later invaders like Celts, Romans, Angles , Saxons, Vikings and Normans.
Apparently we Irish are not even Celtic and instead are more closely related to the Basques in Spain.
Stephen Oppenheimer, a medical geneticist at the University of Oxford, says the historians’ account is wrong in almost every detail. In Dr. Oppenheimer’s reconstruction of events, the principal ancestors of today’s British and Irish populations arrived from Spain about 16,000 years ago, speaking a language related to Basque.
The Celtic cultural myth “is very entrenched and has a lot to do with the Scottish, Welsh and Irish identity; their main identifying feature is that they are not English,” said Dr. Sykes, an Englishman who has traced his Y chromosome and surname to an ancestor who lived in the village of Flockton in Yorkshire in 1286.
Dr. Oppenheimer said genes “have no bearing on cultural history.” There is no significant genetic difference between the people of Northern Ireland, yet they have been fighting with each other for 400 years, he said.
