Smeeton Westerby, in the Gartree Hundred of Leicestershire, was originally two separate settlements. The earlier settlement is Smeeton which comes from Old English smið ‘smith, a worker in metal’ and Old English tun ‘an enclosure; a farmstead; a village; an estate’.
The later settlement, Westerby, is a Scandinavian compound from Old Norse vestr ‘west, westerly’ and Old Norse by ‘a farmstead, a village’. Westerby is presumably an offshoot of Smeeton as the name refers to its location being slightly to the west of Smeeton.
