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