For my Irish relatives and friends I think these finding are about haplogroups while the Celts are the mainstay of Irish heritage, DNA suggests that they weren’t first. You can find a link to Wikipedia at the end of this post to learn more about haplogroups.
According to Irish Central the Celtic origins of the Irish are now disputed by new DNA results.
For a long time we have been taught that the Irish descended from the Celts with the legendary King Milesius considered to be the founder of the Irish people.
DNA studies have apparently revealed that Ireland was settled centuries earlier by survivors of the last ice age (10,000 years ago) from the Basque area of northwest Spain. The closest DNA match with the Irish in all of Europe is with the Basque.
The most recent theory is that they arrived by boat and settled much later in Ireland than in Britain. They did not come from Scotland but from the Basque country in northern Spain. The Irish and the Basque are brothers and according to Irish Central, this is the point where you should start your Irish genealogy.
Click on the link to Celtic Literature Collective to learn about the Book of Invasions. This fascinating book suggests that the Irish originally came from Spain and it was this ancient book that O’Donnell took to the court of Spain, to try to strengthen the ties between the two countries.
