This project is for people who have tested and been assigned the paternal haplogroup I2a2a1 (M284) and also for people who are believed to have belonged to this paternal haplogroup based on tests done on descendants.

Formerly: I2b1a

Defining Mutations

  • M284

Origin

I2b1a (M284) has been found almost exclusively among the population of Great Britain, suggesting that the clade may have arisen in that island. I2b1a is comparatively rare in Ireland. Where it is found in those of Irish descent with Gaelic surnames, and particularly in baronial families with a credible pedigree back to a Cruithin (British) origin, this suggests an ancestor who arrived in Ireland from Celtic Britain. For example it is found in McGuinness and McCartan men descended from the Uí Echach Cobha, a lineage considered Cruithin in the 6th century AD

Distribution

Y-haplogroup I2b1a is a typical British subclade of I.
