Genuine Hawaiian names are unisex. Their literal meaning is usually quite clear, but there may be hidden symbolic meanings known only to the family. Old Hawaiians saw a name as the property of the name-holder, with a power to help or hurt its owner. A meaning that was too apparent might have attracted evil forces. And, just like in Hawaiian poetry, an allusion was considered more beautiful than a plain statement. Surnames did not exist in ancient Hawaii. Early converts might adopt a Christian name and use their Hawaiian name like a surname. In 1860 Kamehameha IV signed the Act to Regulate Names. Hawaiians were to take their father's given name as a surname, and all children born henceforth were to receive a meaningful given name.
