The next logical step is to note that the Scandinavian languages, descended from a North Germanic parent, are more distant historically from English than are Dutch and German, which, like English, are descended from West Germanic.

The degree of actual Dutch influence on the Norwich dialect is somewhat difficult to determine for the rather obvious reason that Dutch and English are closely related languages, both descended from West Germanic, and resemblances between Dutch and forms of English are therefore most usually due not to the influence of Dutch on English, or vice versa, but to their common origin.
