    Any updated M222 maps?

    If I remember right years ago, there was a M222 map that showed a lot of M222 in the northeastern part of Northern Ireland, some other M222 maybe around Donegal, lesser amounts in the rest of Ireland, some in maybe the southwest of Scotland and/or the lowlands of Scotland and maybe a little in England. I have seen other maps since then and they may have varied some from the first one I saw.

    So does anyone have a pretty current, accurate distribution map of M222 in Ireland and the British Isles? If anyone does, thanks.

    Other than the map that was in the original Trinity study there is this one which originated in ScotlandsDNA. Caveats we don't know the sample size per region, also 30% of 30 men is lot less appealing than 30% of 500 men etc.



    The geographic regions aren't ideal particularly in the Irish context, we'd ideally need to spilt out both Dublin and Belfast and to spilt both Leinster and Ulster in two (you could also do same with Munster, though M222 is quite low there).

    Thanks for the interesting map Dubhthach. Seems like they have more M222 in Ulster, way more in Connacht, and a lot more in Leinster than what I have seen before. However, I remember your caveat. Also, if their figures are accurate, then there seems to be more M222 in Ireland as a whole than what they thought before.

    At FTDNA, you can see how many people share an STR signature. This information is categorized by country of origin (of the MDKA, not the tester), and it tells you what percentage of results from that country it accounts for.

    The 12-marker M222 modal signature is 13 25 14 11 11-13 12 12 12 13 14 29. This signature accounts for 3.8 percent of all results that show Ireland as country of origin. Signatures that differ from the modal by 1 account for another 5.3 percent of Irish results. I don't have the ability to look up this information for every set of M222 results, but from what I can see, M222 easily accounts for 15 percent of all Irish results in FTDNA's database and may be higher.

    Now, it's no secret that FTDNA's customers are mostly descended from emigrants. It's possible that the diaspora does not have the same Y-DNA makeup that those in Ireland do.

    Thanks RGM for the interesting ftdna m222 figures. I understand that many of ftdna's database are immigrants, but it still seems that almost any data you look at, that M222 is a significant part of the Irish or/and Northern Irish population. It is still the minority of the population as a whole that has it, but it can be a big chunk of the populace that have it in certain areas, and in certain areas there may be other Irish haplogroups that have a bigger percentage of men in them than M222.

    One would expect CTS4466 and perhaps L226 to probably come out above M222 in a Munster context. Leinster is a bit strange as our definition of Leinster is very different form the historic province.

    Ideally on any of these stats tables/maps we need to get Dublin and Greater-Belfast region spilt out into own item as they have obviously undergone large scale internal migration to over the last 200 years.

    Thanks. I love to hear about different Irish Ydna haplogroups. What surnames are associated with cts4466 and L226? What you say about splitting up Dublin and Belfast makes sense since they must be melting pots of different Ydna haplogroups.

    Indeed well also we must remember that about a quarter of population of Irish state live in Dublin City/suburbs (about 18% of total Island) alone than it really needs to be spilt out. Especially as population there has basically doubled in last 50 years.

    CTS4466 appears to be linked to surnames connected to the Eoghanachta dynastical groups (eg. O'Sullivan, McCarthy, O'Donoghue etc.) basically the group that dominated the southern half of Ireland (Munster and surronding bits) while the Dál Cuinn (Uí Néill and Connachta) dominated the northern half.

    L226 appears specifically linked to the Dál gCais who rose from obscurity to High-Kingship in shape of Brian Boru (d. 1014). Brian is the progenitor of the O'Brien surname of North Munster. His 32-great-grandson (Baron Inchiquin) has been BigY tested and is confirmed L226+
