Do you have a Ysearch ID? I don't see your sample in the M222 project. There's no way to evaluate your statement that the match "falls apart" at 37 markers without one. Missing the M222 modal at 37 markers by 10 or more isn't unusual in the project. <Aside from the fact that this whole Niall thing has been pretty well discredited recently, It's only been discredited in the sense that we do not think all M222 descend directly from Niall. The Niall emphasis in the testing outfits is more a marketing gimmick than anything else. There's plenty of evidence that many of the septs in Ireland said to descend from Niall are M222. You can read all the relevant Trinity collegearticles on the M222 web site. Not knowing the ultimate origins of an SNP group is common to every other major project I've seen. The Irish Type III cluster (Dal Cais) has Irish, Scottish and English matches and no one has the slightest idea why. Dennis Wright runs the project. He thinks his name is Scottish and can't figure out why he's linked to the O'Brien Irish Kings of Thomnd in Ireland.. If there's an answer to that it's probably lost in the miss of time. That's also true of the Leinster cluster. Here you also find lots of matches in Ireland and Scotland with some in England as well. One of their major mysteries is why a large group of Beattys in lowland Scotland match up withe the Kavanagh, Kinesella and O'Byrne chieftains of Leinster. John
