New DNA evidence indicates 10% of Scottish men are descended from the Picts; 3% of Northern Irish men too.

Interesting story here. '...The Picts were assumed to have “disappeared”. But this version of history has since been updated and it is now believed they were overtaken by political events becoming assimilated by incoming Scots invading from Ireland...'
