It is a well known fact that vikings brought many slaves to
Iceland from IRELAND. You can read about it in the following article
under "Ireland".

It is also a well known fact that northern Scotland was settled
by vikings, especially the Orkney and Hebrides Islands. For many
centuries these islands were even a part of the kingdom of Norway. They
spoke Norwegian, were governed from Norway and were of Norwegian
descent.
The article is flawed when it compares the genes of people in the
Orkney Islands and expresses suprise that they found the same
mtDNA as in Iceland. And then, to claim that
Icelanders are related to the Scotch is ridiculous. Vikings left many
genes in Iceland, northern Scotland and the coasts of the British isles.
The Scotch were a tribe that came from Ireland and settled in southern
Scotland. Northern Scotland had been occupied by the PICTS before the
vikings came. Historical records talk of many slaves being brought from
IRELAND to Iceland. Northern Scotland and Ireland are not the same
thing.
Any similarity in DNA is mostly from viking genes being found in
both places. And, to a lesser extent, from Irish genes being found in
both places. Vikings were often described as being redhaired. The
Scottish Highlands have the highest proportion of redheads of any place
on Earth. Norway, Ireland and Iceland have many redheads too. The
Scottish Highlands were settled by vikings and have a viking physical
type. The Scottish Keltic language spread from southern Scotland to
northern Scotland. Norwegian eventually died out, even in the Orkneys.
I have also read that the Irish Gaelic speakers in western Ireland
are actually the descendants of English soldiers settled there by
Cromwell.
