Misson, in the Bassetlaw Wapentake of Nottinghamshire, is a difficult name. It may be a river name, of which the first element has affinities with Danish mysse, Swedish myssene, or Old Norse mysni‘a water-plant (?water-arum)’ either as a simplex name or combined with Old Norse á ‘a river’. Alternatively, the name might derive from Old English mos ‘a bog, a swamp; presumably also moss’.
