With ISLAND dwellers it is normal to see a large amount of convergent
family lines, and the population becomes more typical as time goes on.
One might say that racial traits become evident in Island populations.
If the Island is historically inaccessible to travelers from 'outside"
then that community will eventually become very uniform.
In the case of Eire, it is not so uniform to suggest that a single
population was the source of the main body of occupants. It does appear
however that the isolation and concentration of the R1b1c7 group
regionally upon the island indicates that a relatively uniform
population was isolated in that region for a long time before the other
groups infringed on their area of residency.
This would logically indicate that this group was uninfluenced and in
place before the immigrations to the region by foreign populations, and
that the group was not in commerce with other populations, and had not
wandered far from home. The lack of widespread blooming of teh haplotype
also indicates that when other populations did infringe, they still were
self contained, and seldom 'married out'.
The fact that the base population is still prominent, and centered in
the Northeast region of Ireland indicates that would be the homeland of
Events which would keep them isolated and those later events that made
them start to move out of their enclave should be interesting to research.
I would think that the mid 1800s and the famine were a spreading factor,
and It is likely an event like starvation would account for the forced
movement of this population. I would like to have a look at this
population in the past, isolating them by time frame. I would almost bet
that there were few movements out of the home area before the famines.
Or at least no large movements.
I would also think that wars and other invasions may have pushed a
larger population into a smaller area, and that they were backed into a
corner, and have somehow survived.
