There are a couple of DNA clades that are unique to the Orkneys....which, was a suprise to everyone involved.

This is where the Vikings 'jumped off' on the way to Iceland.

Wow, they did it twice? ;’) The Shetlands were more in that category, probably; the Vikings colonized both.

Could be me. My family was from the area and has a castle in John o’ Groats.

Which means that in much warmer times, the structure was obviously a beach cabana and bar

[Alas Babylon!]

I’m sure you understand, however, that these discoveries predate the Vikings by at least two thousand years. So who were these people? They might even be pre-Celtic. Just as the later people push the British Celts West and North, perhaps these are a remnant of a previous people moved pu from the Celtic invasion?

Perhaps they’re the settlements of a lower sea level North Atlantic people? Red Earth people? Solutrean/Clovis?
