United Irelander: Irish warlord boasts 3 million descendants
Up to three million men around the world could be descended from a prolific medieval Irish king, according to a new genetic study.
It suggests that the 5th-century warlord known as "Niall of the Nine Hostages" may be the ancestor of about one in 12 Irishmen, say researchers at Trinity College Dublin, Ireland. Niall established a dynasty of powerful chieftains that dominated the island for six centuries.
In a study of the Y chromosome - which is only passed down through the male line - scientists found a hotspot in northwest Ireland where 21.5% carry Niall’s genetic fingerprint, says Brian McEvoy, one of the team at Trinity. This was the main powerbase of the Ui Neills, which literally translated means "descendants of Niall".
