Why is that interesting? I haven’t had a chance to watch the video yet. My brother just showed me the DNA results he got the other day and although sibling can be slightly different the Irish is at 30%
Last year I did 23 and Me, found out two interesting things, one that that I share a Hapolgroup that is very rare in the customer groupings of 23and Me only 1-300000 share it and that I share it with one Irish common descendent some 10,000 years ago who was also the Common ancestor for a 4th Century Irish King Ui Neil. My recent heritage was all German, weird stuff.
