Are you a MacDonald herding sheep on your lonely croft? A MacDougall
commuting home from your office job? Or even a MacAlister living a quiet
but humdrum life?
If so, there is every possibility that lurking in your body is the genetic
fingerprint of one of Scotland's greatest warriors - a fearsome man
capable of tearing the heart out of a Viking foe.
An Oxford University scientist has traced the Y-chromosome, which
determines maleness, of the founder of Clan Donald - the great Somerled of
Argyll, who was born around 1100 and drove out the Viking invaders.
Geneticist Bryan Sykes says this microscopic fragment of the fearsome
fighter still lives on in the DNA of half a million clansmen throughout
the world. Indeed Professor Sykes says the Y-chromosome of the Gaelic
warrior, who it seems had Norse blood himself, is so prevalent it could be
among the most successful in the world.
Prof. Sykes and his team made the discovery almost by accident while they
were researching genetic links between the Scots and the Vikings and
looking for Norse Y-chromosomes.
He and researcher Jayne Nicholson had taken thousands of DNA samples from
men in the Highlands and Western Isles, and spotted a group that stood
They were at first puzzled, then Miss Nicholson looked at the donors'
names. These revealed that among the men with the identical Y-chromosomes
were MacDonalds, MacAlisters and MacDougalls.
Prof. Sykes said: "There didn't seem all that much in it until Jayne said
quietly that these clans were related.
"The possibility that this Y-chromosome was inherited from the common
ancestor of the MacDonalds, MacDougalls and MacAlisters was incredibly
They wrote to dozens of those clansmen throughout Scotland, enclosing a
sampling brush for them to collect DNA from inside their cheeks. In the
samples of those who replied, they found a single common Y-chromosome. To
be double sure this was Somerled's, Prof Sykes embarked on a sensitive
piece of research involving the living chiefs of the Clan Donald and their
He said: "I wanted to see if the clan chiefs still alive, whose recorded
genealogies descend from Somerled, also shared the same chromosome. This
was a delicate task. We might find one or more of the chiefs did not have
it - meaning one of their paternal ancestors might have been adopted, or
had not been the biological father of his heir.
He approached Lord Godfrey Macdonald, Sir Ian Macdonald of Sleat, Ranald
MacDonald of Clan Ranald, William McAlester of Loup and Ranald MacDonnell
of Glengary, enclosing a DNA brush.
The result was conclusive: 'They all shared the same chromosome. There was
now no dought we had identified the legacy of Somerled.'
Now the only one whose lineage is in doubt is Somerled himself. Tradition
says he descended from the ancient Irish kings - but Prof. Sykes says the
chromosome proves his Norse ancestry.
