My family came from the Isle of Arran in SW Scotland (http://freepages.genealogy.rootsweb.com/~cafamilies/mcbride/arran.html
My closest DNA match was someone who's family came from N. Ireland, but I am closer to the DNA of one of the 4th century ruler of Scots in the 4th century, Colla Uais, in Ireland before they moved to Scotland as reported at http://www.ourfamilyorigins.com/scotland/founderscots.htm
than I am to the other Irish McBrides.
Are there any other testing services who might have tested more McBrides in Scotland?
Is there any way to access Bryan Sykes results from Scottish DNA testing?
One page which lists a lot testing services is:http://www.genuki.org.uk/big/bigmisc/DNA.html
