I think I should clarify my recent confusing posts! I meant that Morris's pseudonym was 'born' in England as Berwick is officially an English town. I remember Marion Blythman saying that when first married their house was owned by a lady called Berwick and sometimes letters would arrive for Morris as 'Thurso Berwick' (he had already taken the name Thurso). However Morris himself said his pseudonym 'encompassed' Scotland.
