The area between the 38th and 40th parallels (i.e., the Delaware Bay area) as well as the Delaware River from north to south had previously been surveyed and charted by Cornelis Hendricksz from Monnikendam on the ship "Onrust" in 1614, 1615 and 1616. From August until November 1616, the New Netherland Company, which had an exclusive trading patent for the New Netherland territory between 40° and 45° latitude, had tried unsuccessfully to obtain an exclusive patent from the States General of the Dutch Republic for the territory between 38° and 40° latitude.
