Bill, Thank you for the report. It is very interesting. To quote from it: "There is only one McAdam-Milligan. No Grierson-McAdams." I know I am not comparing the same things here--just pointing out the differences. Of the five Mac/McAdam lines, several have matches with a Grierson that's close enough at 37 markers to show up in FTDNA's matches list at the testees' personal pages. Milligans make it into the 67-marker area at those pages, but nobody is close enough to show up at the 111 level there. They and Griersons do appear for all my Mac/McAdams when running searches that go beyond FTDNA's cut-off points though. It's definitely deep ancestry stuff. Some of the matches could be coming from a number of known marriages between McAdams in the Lowlands and Milligans and Griersons there that involved the male taking on his wife's surname. I haven't done any research on that though. I've got seven McAdams who appear to have come from the Lowlands or from Ireland in the chart I'm working on, but four of them haven't tested beyond 12 markers. At a quick glance, they all look like M222, but aren't in the M222 project. Too bad! Allene

Hi, Allene, Some brief comments on your posting. I chose only surnames that were repeated a number of times in my database, that showed a good tendency to cluster, and that were M222. So, it was a sample and not to be considered definitive. In fact, the reason why I cited the associations among the surnames was to show how they might be derived or indicated using the RCC correlation approach -- looking at clusters that contained other surnames on the phylogenetic tree AND looking at the cross-surname intercluster intersections within an RCC time slice matrix. I am sure a very thorough comparison of every McAdams and every Grierson (and their soundex-equivalents) would be much more illuminating. That is what Tei Gordon and I were doing for his Gordons (see <http://mysite.verizon.net/weh8/Gordon20.pdf > and, <http://mysite.verizon.net/weh8/Schwab.pdf>). That approach is a special surname analysis, designed to be more complete. In the work we have done on M222, it was to indicate deeper descriptions of that SNP, not necessarily all the surnames that were in M222, which are many! - Bye from Bill On Jul 23, 2011, at 4:42 PM, Allene Goforth wrote: > Bill, > > Thank you for the report.
