Douglas (and variants) Surname Project - News

May 2013: The old R1b Group Type 2 has been widened to include the old Type 2a subgroup. R1b Group Type 2 is now be defined by a distinctive Y-DNA signature under the haplogroup R-P312:

385b=15,16; 439=11, 447=24, 23; 456=15; 576=19,18; 395S1b=16; 534=17,16; 572=10.

This expanded group probably descends from William de Duglis's reputed father, Freskyn de Moravia. It includes a similar subgroup from the Sutherland DNA Project, there described as 0:3 Moray Firth Group -Haplo=R-P312.

Since 26 January 2011, Y-DNA results in the Douglas Project have been grouped at two different levels.

1.     Haplogroup and Subclade.

The major grouping is by Haplogroup, and Subclade within haplogroup.  People in different haplogroups or subclades cannot be closely related. Men in different major groups are unlikely to have a most recent common ancestor (MRCA) within the last 10,000 years (for major haplogroups) or within 5,000 years or so for subclades within a haplogroup.

If you share a haplogroup or subclade with a person of interest, it is likely that your Most Recent Common Ancestor (MRCA) lived within the last 5,000 years or so.

Results for testers for whom we have not yet found a match, or have too few markers tested to allow reliable matching, will be placed in one of the Unassigned groups.

Haplogroups are determined by a small number of mutations on the Y chromosome, known as Single Nucleotide Polymorphisms (SNPs), or Unique Event Polymorphisms (UEPs). Haplogroups in green have been confirmed by SNP testing.  Haplogroups in red have been predicted by Family Tree DNA based on the individual's STR results and can be confirmed by a Deep Clade SNP test.

2.     Closely related group.

To share an MRCA within recorded history, FTDNA calculates that you need a match within the following degrees of genetic distance (GD), i.e. the number of marker mismatches:

12 markers tested:  0,1

25 markers tested: 0, 1, 2

37 markers tested: 0, 1, 2, 3, 4

67 markers tested: 0, 1, 2, 3, 4, 5, 6, 7

The closer the match, the closer the relationship is likely to be – more or less!  This is only a rough guide, and other information should be factored into the match wherever possible.

 “Within recorded history” is a very loose term. For Scotland, the ancestral home for many of the Douglases, this would be since about 1100AD.

May 2006: A yahoo discussion group has been formed for this group. Membership is open to membership of the DNA project, and to other interested in joining or discussing the results and purposes of the group.

There is now a map on the site showing the origins of the most distant ancestors. Please update your personal page with the co-ordinates of your ancestor's origins. This will then update the map.

I have added a facility to this site for contributions to a fund for the project. I foresee that we will want to obtain DNA samples from some people who can already trace their lines back to William (1174). Some of these people may not have an interest in family history and may not see any reason to have their DNA tested. So we may need to contribute to the cost of the some tests if we are to get the information we need.

So please consider making a contribution to a fund for this purpose. This is a particularly suitable way for females and Non-Douglas surname males who want to see their lines defined.

The Douglas/Gordon connection.
we have found unexpected perfect matches (37 markers) between 2 of our Douglas members and a group of Gordon Surname members. This raises the liklihood of a common ancestor. Was he a Douglas or a Gordon?! We have started a discussion group between the affected members of the 2 families to work on this. Contact the co-ordinators if you are interested in this group.
