David McCoy was a male Human in the 23rd century. He was the father of Doctor Leonard McCoy, chief medical officer of the USS Enterprise and grandfather of Joanna McCoy. (Star Trek III: The Search for Spock) David, like previous generations of McCoys, passed down the family recipe for Southern baked beans to his son, Leonard. Years later, Leonard would reveal that the "secret ingredient" was Tennessee whiskey. Leonard was forced to relive the event as a means to relieve his "pain", in 2287, following an encounter with the Vulcan outcast Sybok. (Star Trek V: The Final Frontier)
