proper name, from Old French Huard, from a Germanic source similar to Old High German *Hugihard "heart-brave," or *Hoh-weard, literally "high defender; chief guardian." Also probably in some cases a confusion with cognate Old Norse Haward, and as a surname also with unrelated Hayward. In some rare cases from Old English eowu hierde "ewe herd."[Howard etymology, Howard origin, 英语词源]
