A close friend and confidant of Benjamin Hornigold, little else is known about John Cockram. Our records indicate that he was a pirate for a few years, prior to 1718, before he surrendered to the king's emissaries. It's likely he fell into pirate-hunting after that, as most reformed ruffians were wont to do.
(Note: I thought it was Guildenstern. Or Rosencrantz. Or ... no, the first one. -DM)
