Fwiw, in the time period you're talking about Wales was just a label for a group of English counties, each fully annexed to England like any other county. The rulers were of Welsh heritage, the Tudors being from Gwynedd in N Wales (I suspect originally Norse, possibly via Ireland).

Strangely, no 'English' people have ruled England since the latter Norman invasion.

Scotland and Wales often try to pretend they weren't part of the Empire and its horrors - in reality their were nobles/toffs/rich nobs from all across GB (at least) doing their part. Barely any of our ancestors were involved in any way other than servitude.

(My family are from both sides of the Anglo-Irish conflicts.)
