Transferred use of the surname of an English noble family. The surname has a large number of possible origins, but in the case of the noble family early forms often have the spelling Haward, and so it is probably from a Scandinavian personal name derived from hā ‘high’ + varðr ‘guardian’. (The traditional derivation from the Old English name Hereweard ‘army guardian’ is untenable.) It is now a widespread given name.
English: habitational name from any of the various places so called. The majority, with examples in at least fourteen counties, are named from Old English horh ‘mud’, ‘slime’ or horn ‘dirt’ + tūn ‘enclosure’, ‘settlement’. One in southern Gloucestershire, however, is named from Old English heorot ‘hart’ + dūn ‘hill’.
