Hi Janis The Scots are literally Irish. Round about 500 AD and for some time before that, there had been a migration of tribes from the North of Ireland across the short passage to the Mull of Kintyre in Argyllshire, Scotland. These people were called the Scotti - believed to be a term (of abuse) used by the Romans. So the original Scots who came from Dal Riata in in Antrim were inhabitants of Ireland. However, at a much later date when the Scots and Picts amalgamated and later combined with the Angles of Lothian and the Britons of Strathclyde, modern Scotland was formed. So it is not surprising that there is Irish DNA in our Scottish ancestors. The Celts, however, came from Central Europe and spread throughout modern day France and into Britain and Ireland. So you will find that you possibly have central European DNA as well. To complicate matters, the west coast of Scotland was subjected to continuous raids by the Vikings over many centuries. Some settled and integrated into the communities and so we have Viking DNA as well (fair hair and blue eyes) As to the name MacCallum, it is very much a Gaelic and Scottish Gaelic name meaning of the family of MacCallein Mor (the Dukes of Argyll). The MacCallums were the hereditary pipers to the Dukes of Argyll. -- *Alan I Cameron*
