Scots in Roman service

[Ti Cl Nero]

Beware of confusing the then-current residents of a geographical area with future or even modern residents. As Mitra points out above, the Dal Raida tribe, progenitors of the Scots, started settling in the southwestern part of what is now Scotland a hundred years or more after the last legions left Britannia.

Hello Ron,
no confusion here, we all agree about what you and Davide say.
One of the Irish tribes harassing the coasts which Ashe mentions are the Atacotti - as I said before, some groups of Atacotti also seem to have been settled in Wales by the Romans themselves (more, 4 units listed in the Notitia Dignitatum were raised among them), and this, according to the article I mentioned earlier about Irish federates, relates to Dyfed, as you say.
Scots, as we all agreed, weren't settled in Britain before legions left, nor we have units of Scots.
Anavionenes, again we agree, are a far different issue.

Simply, since the original question didn't, in my opinion, clearly state whether it referred to Scotti or , more generally, to people then living in "modern Scotland" (which, clearly, is not the same) , I mentioned both.
