In his 1996 book "Bloodline of the Holy Grail: The Hidden Lineage of Jesus Revealed", Laurence Gardner presented pedigree charts of Jesus and Mary Magdalene as the ancestors of all the European royal families of the Common Era. His 2000 sequel "Genesis of the Grail Kings: The Explosive Story of Genetic Cloning and the Ancient Bloodline of Jesus" is unique in claiming that not only can the Jesus bloodline truly be traced back to Adam and Eve but that the first man and woman were primate-alien hybrids created by the Anunnaki of his ancient astronaut theory. Gardner followed this book with several additional works in the bloodline genre.
