Found this link from a friend in France:
My pirate name is:
Captain Jenny Rackham
Even though there’s no legal rank on a pirate ship, everyone recognizes you’re the one in charge. You have the good fortune of having a good name, since Rackham (pronounced RACKem, not rack-ham) is one of the coolest sounding surnames for a pirate. Arr!
