MacGregor DNA Project update January 2010
MacGregor DNA Project – update January 2010
Welcome to the annual update for the MacGregor DNA Project. One of the principal, but happy, difficulties in presenting a report on the MacGregor DNA group is in deciding how to break the results down into small enough groupings so that the diagrams do not become so dense they are unreadable. With 439 results posted as I write this, we remain one of the biggest of the Scottish clan projects. With so many results an attempt to put them all onto one diagram would create something that was not legible. This year I have therefore decided to concentrate on surnames and the surname groups which appear when viewing the Family Tree DNA MacGregor project website (www.familytreedna.com/public/macgregor). As a result I have not made charts which link some haplogroups together (for example there is no specific chart here with both R1b, the Atlantic Modal group – sometimes associated with the ‘celtic’ and the I group, generally applied to the Viking invaders). I am always prepared to generate specific charts for individuals if they would like to contact me.
Before presenting the charts just a few words about how they are generated. I take the raw data from the results page as published by Family Tree DNA and export it into an Excel file. For the purposes of identification I keep the kit number and surname. In many of the charts then each entry is identified by its kit number and part of the surname. For some of the charts however I have cut the surname label down to a letter key only which is given under the chart. With the Excel file complete I copy and paste the whole into the online Y-DNA Comparison Utility created by Dean McGee http://www.mymcgee.com/tools/yutility.html?mode=ftdna_mode using 50% as the Probability, 30 years per generation on average, and the McDonald Mutation Rate figure. I check the box which asks if I want ‘PHYLIP’ data. Once the program generates results I go to the PHYLIP box and copy the results – these I then paste into ‘Splitstree’ a downloadable program that creates the charts www.splitstree.org:

CHART 1 - MacGregor 'bloodline' 67 markers
This chart groups all those in the project who are in the haplogroup R1b (with 67 marker results) but excludes the group of MacGregors who are in Chart 1 with the exception of kit 2124 MacGregor, used for reference purposes. It’s interesting that the program groups McKinlay (17621), a more genetically distant McGregor (28296) and a Skirling (13635) into a sub group, and then connects these with another group of more genetically diverse McGregors, a Greig (9690), a McWhannel (46397), and a Macadam (49834). On the other side of the chart the two Turks are clearly related, the two Starlings (41885 and 52255), the McGehees (74970, 51942, 121911) and Welcher 93788. Peterson 15223 and Reid 153633 seem also to be related more directly.
This chart has the Irish based 67 marker results and shows two discrete groups all having common point of origin and indicating the close genetic ties of the Griers etc. Also on this chart are the Orrs – one in the Irish group and the rest a separate haplogroup R1a, who might also have their genetic origins in the Viking invasion of Ireland but who certainly have Irish connections at the present time.
Again this is 37 marker results. The Grier/Grierson group on the right seem to share a common ancestor within the time of surnames; the Grier/Greer group in the middle has a separate origin and one might conjecture that these are the Griers of S.W. Scotland – connected to the Griersons of Lag. At the far left is a mostly very strongly related Viking group of Griers, and again these might be conjectured to have descended from a Viking settler in East Ireland.
This chart shows McAdam, Magruder, McNies and other participants whose results are listed at the FtDNA results page unattached to any specific group (37 markers). From this chart we can see that there are various groups of McAdams suggesting different origins: 83205 and 82874; 12683, possibly, with 5237, 76324, 144894, 16568, and 71022 (note this is a genetically Irish group); 54141 with 8857; 3714 with Thorn 48842. According to the groupings all other McAdams are singles or more genetically distant. The two McNies are related 66228 and 165873; the two Smiths 35819 and 32132; the Stalling(s) 21898 and 151153. All the Magruders are related 61472, 141702, 141700, 46179. MacGregor 2124 is again included for reference.
This chart contains all the MacGregor bloodline results with 37 markers. Some of the groupings are revealing as will be seen. The key for this is S = Stirling G = Gregory; Macp = Macpherson; C = Campbell; McNa = McNab; J = Jamieson; Ba = Bain; D = Drummond, McF = McFarland. All others are MacGregor however spelt. Kit 2124 is marked with an MM in front.
This chart has all those who are listed in the group ‘Sept or like names’ with 37 markers. Kit 2124 is included for reference and interestingly there is a group of Stirlings with similar DNA to 2124 – but this group of Stirling are quite distant from the earlier group of Stirlings whose ancestor is Robert MacGregor alias Stirling. The Turks are all closely related as are all those at the bottom of the chart whose name is McGhie (however spelt) (and Welcher). Although there are Magees with the typically Irish signature, this group do not have that DNA signature and may be Scottish in origin.
Chart 12b - 'Viking' groups on 67 markers
These two charts show the Viking-related genetic results from the project, the first chart with 37 markers and the second, those of the group who have increased to 67 markers. There are two separate genetic groups: those on the left are I2 and those on the right I1. The testing company Ethnoancestry (www.ethnoancestry.com) says the following about each group:
‘Haplogroup I1(*) is an indigenous European group and is hypothesised to have spread out from the Iberian refugium after the last glacial maximum 18,000 years ago. I1 reaches its highest frequency in Scandinavia and has a decreasing gradient in frequency to the East and to the South and West. I1 is relatively common in the British Isles, having been taken there by Norse and Danish Vikings as well as Anglo-Saxons’.
‘Haplogroup I2a(*) appears to have originated in the Balkans, perhaps from a glacial refugium there; I2a is very common in Croatia and Bosnia today and decreases in frequency across Eastern Europe. A rare offshoot branch of I2a is also found further West, including in the British Isles’.
‘Haplogroup I2b(*) appears to have originated near modern day Germany, where it reaches it peak frequency. I2b is found spread across a broad area of NW Europe including the British Isles, where it has been brought by numerous historical migrations’.
For note – apart from the above results the following participants have different predicted haplogroups: Kammer R1a1; Seuch R1a; Westran R1a1; Bennett N6998 J2; Stivadoros G
