In the 1620's, the Dutch West India Company sent Cornelius Jacobsen Mey with three ships to the Delaware Bay and New York region. During this voyage, he named the Bay's south cape, Cape Cornelius and the north, Cape Mey. The south is now Delaware's Cape Henlopen, while the north still bears his name, although later English settlers altered the spelling. No one has ever found any of it if he did. At least, no one has ever admitted that they have found any of it.
Documented reports note that there was, indeed, pirate activity here.
Through his telescope, he spied a sailing vessel that dropped anchor offshore to allow some men to lower a boat and row ashore. Sometime later, they reappeared on the beach, carrying a chest which they stowed in the yawl boat and returned to the ship. When they reached the ship, they hoisted the chest on board and sailed away. It was rumored that pirates' buried treasure could be found there. That question would have seemed absurd to early area settlers who made their living through whaling in the Delaware Bay.
