Scottish and English: topographic name for someone who lived by an enclosure, Middle English hay(e), heye (Old English (ge)hæg, which after the Norman Conquest became confused with the related Old French term haye ‘hedge’, of Germanic origin). Alternatively, it may be a habitational name from any of various places named with this word, including Les Hays and La Haye in Normandy. The Old French and Middle English word was used in particular to denote an enclosed forest. Compare Haywood. This name was taken to Ireland (County Wexford) by the Normans.
