English (Nottinghamshire and Leicestershire): habitational name from either of two places called Henton (Oxfordshire, Somerset). The Oxfordshire placename derives from Old English hēan, the weak dative form of hēah ‘high’ (originally used after a preposition and article), + tūn ‘farmstead, estate’. The Somerset placename probably derives from Old English henn ‘hen’ + tūn.
