Kirkby in Ashfield, in the Broxtow Wapentake of Nottinghamshire, comes from Old Norse kirkja ‘a church’ and Old Norse bý ‘a farmstead, a village’. Ashfield is an old district name from Old English aesc ‘ash-tree’ and feld ‘open country, unencumbered ground’, though no mention of it has been found except in connection to Kirkby and Sutton in Ashfield, Nottinghamshire.
