Arentz is a Dutch surname, a variant of Arends, which means "son of Arend." Arend itself is a Dutch and German variant of Arnold, a Germanic name composed of the elements arn "eagle" and walt "power," thus meaning "eagle power." Etymology and Origins The surname Arentz derives from the patronymic tradition common in the Netherlands, where names ending in "-s" indicate "son of." Arends (and its variants Arentz, Aarens, Aerse, etc.) ultimately trace back to the personal name Arend, a form of Arnold. Arnold was introduced to England by the Normans, replacing the Old English cognate Earnweald, and though it fell out of use after the Middle Ages, it saw a revival in the 19th century. The root element arn also means "eagle" in Dutch, giving the name a double layer of meaning—both through the etymology of Arnold and the literal Dutch word for eagle.
