It seems likely that all present-day bearers of the name descend from a single family which originated in this place. There is another place of the same name in Cleveland, first recorded in 1273 as Locwyt, from Old English loc(a) + Old Norse viðr ‘wood’, ‘brake’, but it is not clear whether it has given rise to a surname.
