Notes & Trivia
- The genealogy chart shown in the Transformers movie provides an entirely different Witwicky family tree to the one established in the comics, eliminating or renaming most of the above characters. Whether this means characters with such names as Herbert of Clarence Witwicky do not exist in Tyran 707.04 Delta or that Sam's research for his submission was incorrect, is unknown.
