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. For these the TMRCA for each individual listed is for comparing that person to a living person with that haplotype. 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. We are no longer presenting the charts for individual people. The DNA Explained section has charts showing the relationships between our different color-coded groups for R1a and R1b.
For Haplogroup R1b recent discoveries have found several child subhaplogroups of interest to the Clan Donald. Principal among these are numerous ones characterized by the marker L21 and ones characterized by L21 and also M222. Because of extreme overlapping, we have included few 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.
The groups for R1b are listed in the order they appear in the current (March 2015) ISOGG haplotree.
In order to convey the relation betwen haplogroup designations, we have included longer
descriptions of them. For example R1b-DF21 (called R-DF21 by FTDNA) really is
and some are even longer, so we are removing
M207-M173-M343-P25-P297-M269-L23-L51 from all to give R1b-P312-L21-DF13-DF21. Note that FTDNA's designation R-M269 is a very coarse designation. If FTDNA calls someone say R-M269 it means that they know you are classified in the chain as far as M269 but they can't if tell the next SNP is L23 or something else, but based on other criteria we may be able to do so. Prime among these criteria is being an a family group with a unique name like McQuiston.
For Haplogroup R1a the situation is simpler than for R1b. Though several new subhaplogroups have recently
been found, most are restricted to people from eastern Europe. One, however,
designated R1a-YP326 appears to be very closely related to Somerled himself. This mutation
probably appeared in Somerled himself or only a very few generations earlier. See a chart showing
relations near this marker, see here.
R1a-YP326 is R-M207-M173-M420-M459-M512-M417-S224-Z283-Z282-Z284-L448-CTS4179-
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.
