Besides, the Celts WERE originally European, from central Europe, I believe. Yes. My family always claimed we originated in the Rhine valley. However that may be because many of us married PA Dutch, Quakers, and Amish.
I have also heard the Celts never stopped moving west, even past the US and to Australia.
And FWIW, not much, Pictures of my family show smaller, wirey types while pictures of mrs p6’s family are, let’s say, of ...ummm...stockier folk.
Oh, there are also stories from my family of Pictish branches as well as being horse thieves in Kelton Parish, UK.
===================================
With DNA there are no more guesses. I had my DNA done a while back--VERY expensive.
I am 92% Western European and 8% East Asian.
I asked my mother: Huh? Turns out it was from my mother's side. We laughed. Who knows who did what, when and where.
