Yet another paper on Genetics, which I have doubts about.
They sampled according to what I understand from the paper, 2039 individuals from England,
Ireland, Wales and Scotland.
The whole of Ireland and not just Northern Ireland.
By Population from the last available Censuses rounded to the nearest Million, and
assuming the samples are directly related to the population of each country.
England Population 54M - sample = 1613
Scotland Population 6M - sample = 152
Wales Population 3M - sample = 91
Ireland Population 7M - sample = 183
The sample is according to my calculation 0.000030%.
Two small to be the basis of sweeping statements.
Turning to Wales an assumed sample of 91, and again assuming these are evenly split on
traditional counties it gives 7 per County.
Seven from the whole of Pembrokeshire.
How anyone can claim to define differences between Below and Above the Landsker, and the
Landsker was never static on such a small sample is beyond me.
Their Methodology in my opinion is also suspect. They assume that those tested whose all
four Grandparents (Born about 1900 + or - 15 years or so )came from within 80 miles of
each other meant that their ancestors had always lived in the area.
Anyone who has traced his family back to the 1700's or earlier, will know that this is
a false assumption.
I do not subscribe to the theory of Ethnic Cleansing by wave after wave of invaders, but
there is I believe evidence it happened in some areas.
For most of the population it was simply a change of "Overlord-ship".
Most of us however know that many Welshmen from at least the 1500's onwards migrated
to London and other English Cities.
They must have left their Genetic Mark, and the assumption on which the research is based,
and the findings do not take account of later population movements.
My opinions are purely on the basis of what I know about the families I have researched.
I am no expert on DNA Research, and hope that Brian Picton Swann, who is far more
qualified than me, will give his own views from a Scientific Perspective.

Subject: [Dyfed] Landsker line
I'd just like to draw attention to a recent item in Science Daily. This will
definitely not be a surprise to some, but a recently published paper on the
genetic background of the British had some interesting findings. The news
item is at:
The original article is probably accessible in many places, but I looked at
a summary (and comments) here:
The accompanying map is pretty, I imagine, but not so informative for the
colour-blind. But the line through Pembroke is spectacularly obvious.
