- "This guy is rock-and-roll royalty. Not only is he the son of next-gen rock legend Marlene McFly (whose father was the lead singer from Marty and the Pinheads), Marlin also traces his family line back to Chuck Berry's cousin Marvin (of whom we caught just a glimpse during his performance at the Enchantment Under the Sea dance in 1955). Marlin even has famous sci-fi author George McFly in his family tree! He's the coolest."
