Scandinavian place names are found in varying densities over much of the British Isles. They occur in the Northern and Western Isles and along the northern, western and north-eastern seaboard of Scotland, in the Isle of Man, in eastern, northern and north-western England, as well as in the northern and southern seaboard of Wales and along the eastern seaboard of Ireland. It is impossible to date the coining of the place names concerned but it seems reasonable to assume that the first settlements arose some time after the first Viking raids in the British Isles.
