I rest my case. I have no known 1st or 2nd degree relatives with anything other than O positive blood type. My Y DNA clan matched very high with the Basques and Iberians.
"And what of the Celts we know the Irish, Scots and Welsh? Scholars have traditionally placed their origins in Iron Age Central Europe, but Oppenheimers new data clearly show that the Welsh, Irish and other Atlantic fringe peoples derive from Ice Age refuges in the Basque country and Spain. They came by an Atlantic coastal route many thousands of years ago, though the Celtic languages we know of today were brought in by later migrations, following the same route, during Neolithic times."
