Here's a description of the contestant's attempt. Someone's probably working on collecting some images to illustrate it.

Dave brings in a picture of the Hollywood actor, Cary Grant. Although Greg doubts that they are actually related, Alex displays a family tree which indicates that Cary Grant’s cousin had married Dave’s great-grandmother’s niece. Dave earns five points.
