Christopher Moody was a member of Howell Davis's crew aboard the sloop Buck after Davis staged a mutiny, took over the vessel, and turned to piracy in 1718. Davis sailed to the western coast of Africa where he cooperated with fellow pirates Jeremiah Cocklyn and Olivier Levasseur.
This was the only time the two Moodys potentially crossed paths: William Moody had recently ejected the quarrelsome Cocklyn but was in turn marooned by his own sailors. Davis was killed during an attempted raid on Principe and Roberts was elected Captain in his place.
