Brother Robin A O’Donnell’s DNA and mine !

Haplogroup R1b1b2a1a2f2 and HV (which is of course the same as me and our girl Timoni) – Very interesting!

R1b1b2a1a2f2 reaches its peak in Ireland, where the vast majority of men carry Y-chromosomes belonging to the haplogroup. Researchers have recently discovered that a large subset of men assigned to the haplogroup may be direct male descendants of an Irish king who ruled during the 4th and early 5th centuries. According to Irish history, a king named Niall of the Nine Hostages established the Ui Neill dynasty that ruled the island country for the next millennium.

Northwestern Ireland is said to have been the core of Niall’s kingdom; and that is exactly where men bearing the genetic signature associated with him are most common. About 17% of men in northwestern Ireland have Y-chromosomes that are exact matches to the signature, and another few percent vary from it only slightly. In New York City, a magnet for Irish immigrants during the 19th and early 20th century, 2% of men have Y-chromosomes matching the Ui Neill signature. Genetic analysis suggests that all these men share a common ancestor who lived about 1,700 years ago. Among men living in northwestern Ireland today that date is closer to 1,000 years ago. Those dates neatly bracket the era when Niall is supposed to have reigned.

Outside Ireland, R1b1b2a1a2f2 is relatively common only along the west coast of Britain.


HV (that’s me!)

HV*, a sister of the common European haplogroups H and V, arose in the Near East not long after modern humans left Africa more than 40,000 years ago. From the Near East, the haplogroup appears to have spread into North Africa, Russia, eastern Europe and the Italian peninsula, which has an unusually high concentration of HV*. The largest concentration of HV*, however, appears to be in Iraq. The haplogroup is also common in other regions of the Near East, particularly the Caucasus Mountains. There are four major daughter lineages encompassed within haplogroup HV*, known as HV1, HV2, HV3, and HV4.
