I wonder that are there any tribes of Nords, like the Skaal in Solstheim? I wonder that there might be some near the Northern coast of Skyrim, or in the hills of Reach.(I know Reach is filled with Forsworn)
I wonder if there are Nordic tribes around. That idea is very interesting to me.
I don't think there are Nordic tribes around because I have never seen any other than the Skaal. Pretty much all of the Nords of Skyrim have adopted the customs and religion of the Empire, as evidenced by their reverence for the Divines and for Talos, who was the founder of the Empire. Despite all the "Skyrim for the Nords" talk, they've been a part of the Empire for so long that just about every vestige of the old ways of Atmoran culture has been eclipsed by a more civilized and modern society
There are Nordic clans (i.e. Grey Mane, Battle Born, Snow Shod), though I believe these are merely family lines. Still, I imagine many of them stretch back far in time, to when the first settlers from Atmora came to Tamriel. Their societies probably began as small settlements, though that's not quite the same as a tribe, at least in the sense you are implying.
