*Regarding 392, I have casually observed that there is a much higher percentage of a mutation up to 15 among M222+ than there is with any other single sub-clade that I have observed among the tested results available in the public view of FTDNA, Ysearch or other such as Sorenson, World Families, etc. It also seems that among those results that there are also a good percentage of off modals in the 1--37 marker range with many of them showing up with in the first 25. A lot of those 15's seem to be either Scot and/or Scot-Irish -- Davidson has many although it is unknown how related those that tested are. I think there may be a Scot Kennedy as well. I found a near identical Match to 197231 McConnaughey of another McConnaughey who tested through Sorenson (15 at 392) -- couldn't see the actual string there but it was 1+/- off at 19 (394)& 1/2 +/- off at 385. Have not been able to talk to this fellow to see if he is lineage attached. So this could be strictly lineage related skewing the percentage or geographic which might be indicative of something else. With in the related lineage another result in 216751 McConnaughey. That mutation to 15, however could be telling down the road. Might indicate something towards a downstream division, and if it is might also help in further clade age calculations. I have speculated that those results yielding this mutation to 15 are also indicative of overall lineage and/or clade age, but that is simply something I've been thinking as there aren't enough of them over all to really determine that in view of anything beyond the raw data*.*In other words it hasn't really been looked at* as being an indicator of anything, I don't believe. The percentages for 392 were striking. In addition to those at 14, another 23 were one step higher at 15. Other than these there were 6 at 13 and 1 at 11 (M222+, it's not a mistake).. If you added the 14 and 15 figures together you'd get 98.8% of the project with 14 or higher. *I was fortunate enough to talk with David Wilson not too long ago -- with-in the last month. He indicated to me that he thought the 1--37 set was the best analytical set for M222+* Overall, the strongest percentages of matches is found within the 1-25 marker set. In the 37-67 set 413a at 93.1% looks promising.*I think I agree w/you on this.* *I've also casually observed 390. I'm not entirely certain what that tells us. Might be geographic, and perhaps the +/- steps should be looked at individually in terms of geography to see.* I was a little surprised at the relatively low percentages for 390 (86.1%). That is mainly caused by a surprising number at 24 (73). Another 25 were 26 or higher. *Thank you John for calculating and posting this. Susan* .
