Fictional genealogy

A fictional genealogy is an elaborate fictional family or set of
inter-related fictional families. One early version is the vast genealogy of
gods and heroes in Greek mythology. One recent example is J.R.R. Tolkien who
created many family trees for his Lord of the Rings characters. The Wold
Newton family, created by Philip Jose Farmer, includes many fictional
characters from the nineteenth and twentieth centuries like Sherlock Holmes
and Tarzan.

Other fictional families:

   * The Collins family - The family from Dark Shadows
   * The Duck family, The Clan McDuck and the Coot Kin- The extensive family
     of Donald Duck
   * The Skywalker family - Darth Vader and his descendents in Star Wars
