Barnby in the Willows, in the Newark Wapentake of Nottinghamshire, most likely comes from the Old Norse elements barn ‘child’ and by ‘farm, settlement’. Its meaning, ‘farmstead of the children’, may indicate joint inheritance by the offspring. Alternatively, the first element of the name could come from the Old Danish male personal name Barni. The affix is added at a later date and means ‘among the willow-trees’ and could be connected to its low location by the river Witham. The place-name has the same etymology as Barnby Moor, in the Bassetlaw Wapentake of Nottinghamshire.
