Results obtained without a search are sorted with respect to the TMRCA from the "group modal", which has the most common value for each marker. Results of a search are sorted with respect to TMRCA from the search target. Note that they are sorted by TMRCA, not by the number of mismatched markers. For results tables without a search (header row says "Group Modals") the TMRCA column in that same row gives the TMRCA for the whole group, that is, the estimated number of generations since the common ancestor for everyone in the group lived. For the technically inclined, we also list the genetic distance, using the infinite alleles model, which is also used for the TMRCA calculations. For people with 67 Family Tree DNA markers, these calculated times increased somewhat on June 3, 2008, when newly measured marker mutation rates, which are slower than previously assumed, were adopted.
In the results for R1a, the haplogroup of Somerled, the names or codes of our Clan Chiefs, Iain Godfrey Macdonald of Sleat &CXYIE, Ranald MacDonell of Glengarry &5XOBA, and Ranald Alexander MacDonald of Clanranald &EDC4L, are color-coded blue. Allan Douglas MacDonald of Vallay &BATPB, Chieftain of the Vallay line, is colored green.
In the past we have made up graphical network charts which show the most likely relationships between all our participants who have 37 or 67 markers. Due to the increased size of our project this has become unwieldy for R1b at 37 markers. There are links to see popups of these relationship charts at the right. The DNA Explained section has a discussion of how these charts are created. Different colors are used for different groups. For R1b the second color is represented by a ring color. The unassigned people are yellow. The color of the pies on these charts corresponds to the color of the separator bar below the headings on the tables; the table sections correspond exactly to the chart colors.
For Haplogroup R1b recent discoveries have found several child subhaplogroups of interest to the Clan Donald. Principal among these is the one characterized by the marker L21 and one characterized by L21 and also M222. The Royal House of Scotland, the Stewarts (Stuarts) lies within L21, however, none of our participants with 37 or more markers lie close the this haplotype, though one with 25 markers, &TDMW3, probably does. Because of extreme overlapping, we have not included people with 12 or 25 markers in these groups. Such people really should upgrade to at least 67 markers. They can, of course, use our search function to find which group they most closely resemble.
For Haplogroup R1a the situation is simpler. Though several new subhaplogroups have recently been found, most are restricted to people from eastern Europe. One, however, first found in our Webmaster, and designated R1a-L176.1, appears to be very closely related to Somerled himself. This mutation probably appeared in Somerled himself or only a very few generations earlier.
People get placed in the yellow "undifferentiated" groups for several reasons. One reason is that they really are clearly different from everybody else. Another reason is that they don't have enough markers measured to be actually sure which group to place them in; we are now classifying only people with 37 or more markers. The final reason is that, while to the eye they may look to be grouped, the computer algorithms say that the grouping is uncertain.
For privacy reasons we have not listed participants' FTDNA numerical codes. Those that are on Ysearch have their Ysearch codes listed on the result tables. All participants have been assigned a Clan Donald code, similar in form to Ysearch ones but different, and denoted by an & sign. If you do not know where you are on these tables or charts, use our "Search" function above. Clicking on a person's Ysearch code will take you to their personal page on Ysearch, so you may see their genealogical information. Clicking on their Clan Donald code will generate results tables sorted with that person at the top and other persons in increasing order of TMRCA. The results of this are restricted to a limited number of generations, which is set using the "Search" page. This feature is a primary method of determining family associations.
Different companies have to some extent gone to the same numerical nomenclature system. Where differences remain we have applied appropriate conversions to convert to the FTDNA system.
