I work with Anglo-Saxon works published in the mid-to-later late 17th century, but I think my expertise may be helpful here.

I'm on mobile at a boring brunch right now. I will provide sources when I can access my one note at home.

There was a resurgence of pro-Anglo-Saxon sentiment in the wake of the Glorious Revolution and particularly after the rise of the Hanoverian dynasty in the early 18th century. The reason is that the English tried to tie their new Germanic monarchy to a Germanic past--i.e. the Anglo-Saxons. They also pointed to their Germanic past as a Golden Age that was disrupted by foreign invaders--the Normans, Angevins, and eventually the Catholic (or Catholic-sympathizing) late Stuarts. So a return to a Continental, Germanic monarchy was simply the resumption of the way things should be. See the work of Bishop Edmund Gibson for more on this.
