The town's name, in Dutch, officially means "Moneyland", referring to the Dutch settler's original assumption that the large amount of sand in the area could generate a profitable glass industry. Other influences on the name could have also been the province of Gelderland, in The Netherlands. It may have been Gelterland or Gelterlan in the original Dutch.
