<P> James Strickland (portrayed by James Tolkan in Back to the Future Part III) is the chief marshal of Hill Valley in 1885 and the grandfather of Mr. Strickland . He also has an unnamed son (portrayed by Kaleb Henley), who will become Gerald Strickland's father . </P> <P> Edna Strickland, in Back to the Future: The Game, is the sister of Gerald Strickland . She is somewhat nicer than her brother, but still set in her ways towards upholding strong morals and abolishing crime and laziness . After Marty alters her original timeline, Edna marries Kid Tannen who becomes the father of Biff Tannen . </P> <P> Jennifer Jane Parker is the girlfriend (and, in 2015 in Back to the Future Part II, the wife) of Marty McFly . </P> <P> The character was played by Claudia Wells in Back to the Future . However, Wells was not available to film the sequels for personal reasons, and the role was recast to Elisabeth Shue although Wells reprised her role as Jennifer in Back to the Future: The Game as a punk rock version of her character . Consequently, the opening scene of Back to the Future Part II was re-shot with Shue taking Wells' place, rather than using the ending of Back to the Future . In the spin - off Back to the Future: the Animated Series, Jennifer was voiced by Cathy Cavadini . </P>
