Family is crucial in the Star Wars universe. A lot of the saga is about where characters come from. Although, Star Wars: The Last Jedi tried to change that with the film's reveal, or lack thereof, of Rey's birth parents. That could all change of course with J.J. Abrams' Star Wars: Episode IX. However, The Last Jedi aside, family and characters' heritage has always been held in high regard in George Lucas' space opera movie franchise.
