One in Hampshire has as its first element Old English h(e)all ‘hall’, ‘manor’, or healh ‘nook’, ‘corner of land’. However, the surname is common in South Yorkshire and Nottinghamshire, and may principally derive from a lost place near Sheffield named Hawley, from Old Norse haugr ‘mound’ + Old English lÄ“ah ‘clearing’.
