Ashley, Greetings and welcome. I find the names of places are often quite interesting you mention salisbury and Usk, where I lived in Alaska we had an Usk Bay. and a Salisbury Sound, However most of the names in the general area were from the Russian heritage and of course Native Tlinget and Haida.
With Kilpatrick , Fitzpatrick, and Brenans in my line of fore folks I guess I'm mostly Irish. But my father was born within hearing range of the Bell in London that makes one a Cockney, so if they ever go back to discriminating against the Irish I can say I,m English!
