Ireland was invaded by Vikings for 200 years, some settled in Ireland and married Irish women and there were large numbers of Irish women who were returned to Scandinavia as slaves. Travel between Ireland and Scandinavia was common so the Irish have high levels of Viking DNA and conversely a good number of Scandinavians have Irish DNA.

It IS an artifact. You should read how these companies do their analysis. The reference panels aren't big enough to get statistically accurate results in the low percent range.

It's also rather irrelevant, IMHO. There was enough genetic mixing in northern Europe, even more than elsewhere in Europe (because of ease of transportation by water) that no northern European population is genetically "pure".

I'll step out of this debate now. Think what you will, and enjoy the fun, because genealogy should be fun! And interesting.

I don't think it's because reference panels aren't big enough, I think it's because there's too much genetic overlap among neighboring regions. It actually seems the bigger the reference panel gets, the more overlap it shows, the more it become obvious there's not enough genetic distinction to always tell them apart.

This is not my personal experience, but it's definitely an amazing story that involves a 23andme test. Good thing they have a video or you can read the story.
