I did Ancestry DNA a couple of years ago and found I am so British/Scottish/Scandinavian it's almost embarrassing. There is a small amount of western European and smatterings - virtually negligible amounts - of Mediterrean/eastern European genes for me. I am Viking to the core, LOL!
I did find out lately that my Scottish family lines (numerous on both my parents' sides) are directly traceable to Robert The Bruce, whose original name was Robert VIII de Bruce. He was also called Robert I. Born in 1274 he became King of Scotland from 1306 to 1329 (when he died). He freed Scotland from English rule.
Always "knew" I was 'somebody', LOL!
