Gaelic Icelanders

Note the positioning of the SSG-A4 sample,
she appears to be super drifted in the direction
of the “Celtic” cluster.

With my sincerest thanks to David of the Eurogenes blog, we are now for the first time ever able to look at at least two relatively pure medieval Irish samples from the mixed Norse/Gaelic colony of Iceland.
Unfortunately they are both very low quality samples, but beggars cannot be choosers of course.
Both samples show a relatively high degree of drift with modern Irish, particularly Irish from Ulster which seems to have been where most of the Gaelic settlers came from.
