Results may be viewed in several ways. First, the tables showing all results may be viewed using the menu at the right. Displaying this many results at once can be rather sluggish; if asked to continue, do so. Results may also be viewed in restricted sets, grouped as Haplogroups E, G, I, and J, or all of R1a, or all of R1b (also somewhat slow), or just the part of R1b classified into small groups, or just the unclassified R1b results.

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.

For several haplogroups we have made up graphical network charts which show the most likely relationships between our participants who have 37 or 67 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. The undifferentiated people are yellow. The color of the dots 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.

The pale pink (&OFVDB) ,brown (&BAPAY, McCutcheon), and maroon (McQuiston) R1b groups are clear subsets of the Red "Scots" one. According to recent research it appears that the green R1b group is also a subset of the red one. The dark blue-green (&MH7QB) one is not. The R1b green "Northwest Irish" area contains the haplotype of Niall of the Nine Hostages, though none of our participants are known to be in his male line.

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; this applies to lots of people who have only 12 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.

How to find yourself in our results tables and charts

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.

A note on marker number conventions

Unfortunately different companies sometimes give different numbers of repeats for certain markers, even for the same person. We use the convention of Family Tree DNA for their markers, which are 393 through 565 on our charts. For markers 434 through DYF411b we use the convention of what was formerly DNA-Fingerprint, now the "Advanced Orders" (selectable by individual marker) section of Family Tree DNA. For markers 494 through 638 we use the Ethnoancestry numbers. The following table shows what the numbers for the Webmaster PUAP2 (currently thought to be the same as Somerled) would be for different companies. Blank entries are the same value as for the Clan Donald (PUAP2) row. The same additive or subtractive conversions would be employed for other people.

On April 22, 2007, Ethnoancestry changed their nomenclature for 9 markers. On April 23, we changed to this nomenclature for those markers which are unique to Ethnoancestry. We did not change nomenclature for the markers which are in common between Ethnoancestry and Family Tree DNA, since we continue to use the FTDNA values. These changes are indicated on the chart below.
