Family name origins & meanings
- Spanish : topographic name for someone who lived by an orange grove, from Spanish naranjo ‘orange tree’ (from naranja ‘orange’, Arabic nāránjya), or a habitational name from a place named Naranjo in A Coruña and Códoba provinces. (The word orange reached English from Spanish via Old French and Old Provençal, in which languages the initial n- had already been sporadically lost.)
