Well, the older English were Angles, Frisians, that sort of thing. They were blond too
Interestingly, I think the Gondorians are fantasy-Rome, but Minas Tirith is fantasy-Byzantium. The description of the Siege of Gondor is redolent of the story of the fall of Constantinople (aka Byzantium) in the 1400s. The backstory of Gondor and its wars also connects us to the real world story of the Pechenegs (an eastern tribe of raiders who rode large wagons aka "wains")
Constantinople/Byzantium also connects us in other ways. The emperor of Constantinople was guarded by a bunch of Viking warriors (Varangians), who were originally Swedish. Later, however, the ethnic composition changed, and the Varangians were largely English.
And, my favourite, "Varangian" is a slavic word, for Viking, or the Swedes. (Another word was Rus, hence Russia). But the eastern slavic word for Varangians?
Variag. Sound familiar?
