The origins of the Edenfield place name are not entirely clear, but it seems extremely unlikely that it derives from "fields of Eden" or similar. Given the large number of Norse-derived place names in Rossendale and bearing in mind that documents from the 17th century and older spell the name as Aydenfield or some variant of this, a likely etymology is the Norse "øy" (riverside ground/island; see for instance the village of Øyer) + "tun" (farmstead) + field; in other words, the land belonging to the farmstead by the river (Irwell).
